wpf怎么openfiledialog

Microsoft.Win32空间下有OpenFileDialog的。

我的问题就是因为OPENGL不支持...

是你的显卡 驱动 问题, 你换个显卡驱动 绝对可以解决问题!

dont dead open inside是什么意思?!

是一个梗,有些人看到此图会下意识念成dont dead open inside(变成病句)实际上是don"t open dead inside。不要开门,内有行尸。

dont dead open inside什么意思

那是dont open dead inside...门上的字是竖着看的

什么是 open path gas detector

vbox怎么创建建openwrt系统虚拟机

方法如下准备好需要版本的openwrt.vmdk。打开VirtualBox,新建虚拟机并填写相关参数。至此,下面的步骤分为两种。直接创建虚拟硬盘。不添加虚拟硬盘。在文件中找到了添加进来,并选择。在系统中将硬盘启动调至最前。安装成功。打开安装好的VirtualBox,以下简称vb(不是编程的vb哦)。点击【新建】键入虚拟机名称选择内存大小,一般1G差不多,本机内存多的,可以多分点给虚拟机虚拟硬盘选择创建新的虚拟硬盘。如果之前搞过,可以选择之前的*.vdi。以上一般默认就可以,点击【创建】分配虚拟硬盘大小,硬盘一般不成问题吧,大小20G-30G差不多。动态分配和固定大小都可以,无碍。点击【创建】

trun on the radio 还是open the radio

turn on the radioturn on,有开启,启动,那种内容打开的意思,如turn on the radio。open用于表示,开或者是关的那种状态的开,如open your mouth。-------------如有帮助请采纳, 如需帮助可追问,谢谢。

opencv怎么确定人脸各部分的位置

1.1.介绍Introduction从OpenCV2.4开始,加入了新的类FaceRecognizer,我们可以使用它便捷地进行人脸识别实验。本文既介绍代码使用,又介绍算法原理。(他写的源代码,我们可以在OpenCV的opencvmodulescontribdocfacerecsrc下找到,当然也可以在他的github中找到,如果你想研究源码,自然可以去看看,不复杂)目前支持的算法有 Eigenfaces特征脸createEigenFaceRecognizer() Fisherfaces createFisherFaceRecognizer() LocalBinary Patterns Histograms局部二值直方图 createLBPHFaceRecognizer()下面所有的例子中的代码在OpenCV安装目录下的samples/cpp下面都能找到,所有的代码商用或者学习都是免费的。1.2.人脸识别Face Recognition对人类来说,人脸识别很容易。文献[Tu06]告诉我们,仅仅是才三天的婴儿已经可以区分周围熟悉的人脸了。那么对于计算机来说,到底有多难?其实,迄今为止,我们对于人类自己为何可以区分不同的人所知甚少。是人脸内部特征(眼睛、鼻子、嘴巴)还是外部特征(头型、发际线)对于人类识别更有效?我们怎么分析一张图像,大脑是如何对它编码的?David Hubel和TorstenWiesel向我们展示,我们的大脑针对不同的场景,如线、边、角或者运动这些局部特征有专门的神经细胞作出反应。显然我们没有把世界看成零散的块块,我们的视觉皮层必须以某种方式把不同的信息来源转化成有用的模式。自动人脸识别就是如何从一幅图像中提取有意义的特征,把它们放入一种有用的表示方式,然后对他们进行一些分类。基于几何特征的人脸的人脸识别可能是最直观的方法来识别人脸。第一个自动人脸识别系统在[Kanade73]中又描述:标记点(眼睛、耳朵、鼻子等的位置)用来构造一个特征向量(点与点之间的距离、角度等)。通过计算测试和训练图像的特征向量的欧氏距离来进行识别。这样的方法对于光照变化很稳健,但也有巨大的缺点:标记点的确定是很复杂的,即使是使用最先进的算法。一些几何特征人脸识别近期工作在文献[Bru92]中有描述。一个22维的特征向量被用在一个大数据库上,单靠几何特征不能提供足够的信息用于人脸识别。特征脸方法在文献[TP91]中有描述,他描述了一个全面的方法来识别人脸:面部图像是一个点,这个点是从高维图像空间找到它在低维空间的表示,这样分类变得很简单。低维子空间低维是使用主元分析(Principal Component Analysis,PCA)找到的,它可以找拥有最大方差的那个轴。虽然这样的转换是从最佳重建角度考虑的,但是他没有把标签问题考虑进去。[gm:读懂这段需要一些机器学习知识]。想象一个情况,如果变化是基于外部来源,比如光照。轴的最大方差不一定包含任何有鉴别性的信息,因此此时的分类是不可能的。因此,一个使用线性鉴别(Linear Discriminant Analysis,LDA)的特定类投影方法被提出来解决人脸识别问题[BHK97]。其中一个基本的想法就是,使类内方差最小的同时,使类外方差最大。近年来,各种局部特征提取方法出现。为了避免输入的图像的高维数据,仅仅使用的局部特征描述图像的方法被提出,提取的特征(很有希望的)对于局部遮挡、光照变化、小样本等情况更强健。有关局部特征提取的方法有盖伯小波(Gabor Waelets)([Wiskott97]),离散傅立叶变换(DiscreteCosinus Transform,DCT)([Messer06]),局部二值模式(LocalBinary Patterns,LBP)([AHP04])。使用什么方法来提取时域空间的局部特征依旧是一个开放性的研究问题,因为空间信息是潜在有用的信息。1.3.人脸库Face Database我们先获取一些数据来进行实验吧。我不想在这里做一个幼稚的例子。我们在研究人脸识别,所以我们需要一个真的人脸图像!你可以自己创建自己的数据集,也可以从这里(http://face-rec.org/databases/)下载一个。AT&TFacedatabase又称ORL人脸数据库,40个人,每人10张照片。照片在不同时间、不同光照、不同表情(睁眼闭眼、笑或者不笑)、不同人脸细节(戴眼镜或者不戴眼镜)下采集。所有的图像都在一个黑暗均匀的背景下采集的,正面竖直人脸(有些有有轻微旋转)。YaleFacedatabase A ORL数据库对于初始化测试比较适合,但它是一个简单的数据库,特征脸已经可以达到97%的识别率,所以你使用其他方法很难得到更好的提升。Yale人脸数据库是一个对于初始实验更好的数据库,因为识别问题更复杂。这个数据库包括15个人(14个男人,1个女人),每一个都有11个灰度图像,大小是320*243像素。数据库中有光照变化(中心光照、左侧光照、右侧光照)、表情变化(开心、正常、悲伤、瞌睡、惊讶、眨眼)、眼镜(戴眼镜或者没戴)。 坏消息是它不可以公开下载,可能因为原来的服务器坏了。但我们可以找到一些镜像(比如 theMIT)但我不能保证它的完整性。如果你需要自己剪裁和校准图像,可以阅读我的笔记(bytefish.de/blog/fisherfaces)。ExtendedYale Facedatabase B 此数据库包含38个人的2414张图片,并且是剪裁好的。这个数据库重点是测试特征提取是否对光照变化强健,因为图像的表情、遮挡等都没变化。我认为这个数据库太大,不适合这篇文章的实验,我建议使用ORL数据库。1.3.1. 准备数据我们从网上下了数据,下了我们需要在程序中读取它,我决定使用CSV文件读取它。一个CSV文件包含文件名,紧跟一个标签。/path/to/image.ext;0假设/path/to/image.ext是图像,就像你在windows下的c:/faces/person0/image0.jpg。最后我们给它一个标签0。这个标签类似代表这个人的名字,所以同一个人的照片的标签都一样。我们对下载的ORL数据库进行标识,可以获取到如下结果:./at/s1/1.pgm;0./at/s1/2.pgm;0..../at/s2/1.pgm;1./at/s2/2.pgm;1..../at/s40/1.pgm;39./at/s40/2.pgm;39想象我已经把图像解压缩在D:/data/at下面,而CSV文件在D:/data/at.txt。下面你根据自己的情况修改替换即可。一旦你成功建立CSV文件,就可以像这样运行示例程序:facerec_demo.exe D:/data/at.txt1.3.2 Creating the CSV File你不需要手工来创建一个CSV文件,我已经写了一个Python程序来做这事。[gm:说一个我实现的方法如果你会cmd命令,或者称DOS命令,那么你打开命令控制台。假设我们的图片放在J:下的Faces文件夹下,可以输入如下语句:J:FacesORL>dir /b/s *.bmp > at.txt然后你打开at.txt文件可能看到如下内容(后面的0,1..标签是自己加的):。。。。J:FacesORLs11.bmp;0J:FacesORLs110.bmp;0J:FacesORLs12.bmp;0J:FacesORLs13.bmp;0J:FacesORLs14.bmp;0J:FacesORLs15.bmp;0J:FacesORLs16.bmp;0J:FacesORLs17.bmp;0J:FacesORLs18.bmp;0J:FacesORLs19.bmp;0J:FacesORLs101.bmp;1J:FacesORLs1010.bmp;1J:FacesORLs102.bmp;1J:FacesORLs103.bmp;1J:FacesORLs104.bmp;1J:FacesORLs105.bmp;1J:FacesORLs106.bmp;1。。。。自然还有c++编程等方法可以做得更好,看这篇文章反响,如果很多人需要,我就把这部分的代码写出来。(遍历多个文件夹,标上标签)]特征脸Eigenfaces我们讲过,图像表示的问题是他的高维问题。二维灰度图像p*q大小,是一个m=qp维的向量空间,所以一个100*100像素大小的图像就是10,000维的图像空间。问题是,是不是所有的维数空间对我们来说都有用?我们可以做一个决定,如果数据有任何差异,我们可以通过寻找主元来知道主要信息。主成分分析(Principal Component Analysis,PCA)是KarlPearson (1901)独立发表的,而 Harold Hotelling (1933)把一些可能相关的变量转换成一个更小的不相关的子集。想法是,一个高维数据集经常被相关变量表示,因此只有一些的维上数据才是有意义的,包含最多的信息。PCA方法寻找数据中拥有最大方差的方向,被称为主成分。算法描述Algorithmic Description令 表示一个随机特征,其中 .计算均值向量 计算协方差矩阵 S计算 的特征值 和对应的特征向量 对特征值进行递减排序,特征向量和它顺序一致. K个主成分也就是k个最大的特征值对应的特征向量。x的K个主成份:其中 .PCA基的重构:其中 .然后特征脸通过下面的方式进行人脸识别:A. 把所有的训练数据投影到PCA子空间B. 把待识别图像投影到PCA子空间C. 找到训练数据投影后的向量和待识别图像投影后的向量最近的那个。还有一个问题有待解决。比如我们有400张图片,每张100*100像素大小,那么PCA需要解决协方差矩阵 的求解,而X的大小是10000*400,那么我们会得到10000*10000大小的矩阵,这需要大概0.8GB的内存。解决这个问题不容易,所以我们需要另一个计策。就是转置一下再求,特征向量不变化。文献 [Duda01]中有描述。[gm:这个PCA还是自己搜着看吧,这里的讲的不清楚,不适合初学者看]OpenCV中使用特征脸Eigenfaces in OpenCV给出示例程序源代码#include "opencv2/core/core.hpp"#include "opencv2/contrib/contrib.hpp"#include "opencv2/highgui/highgui.hpp"#include <iostream>#include <fstream>#include <sstream>usingnamespace cv;usingnamespace std;static Mat norm_0_255(InputArray _src) {Mat src = _src.getMat();// 创建和返回一个归一化后的图像矩阵:Mat dst;switch(src.channels()) {case1:cv::normalize(_src, dst, 0,255, NORM_MINMAX, CV_8UC1);break;case3:cv::normalize(_src, dst, 0,255, NORM_MINMAX, CV_8UC3);break;default:src.copyTo(dst);break;}return dst;}//使用CSV文件去读图像和标签,主要使用stringstream和getline方法staticvoid read_csv(const string& filename, vector<Mat>& images, vector<int>& labels, char separator =";") {std::ifstream file(filename.c_str(), ifstream::in);if (!file) {string error_message ="No valid input file was given, please check the given filename.";CV_Error(CV_StsBadArg, error_message);}string line, path, classlabel;while (getline(file, line)) {stringstream liness(line);getline(liness, path, separator);getline(liness, classlabel);if(!path.empty()&&!classlabel.empty()) {images.push_back(imread(path, 0));labels.push_back(atoi(classlabel.c_str()));}}}int main(int argc, constchar*argv[]) {// 检测合法的命令,显示用法// 如果没有参数输入则退出!.if (argc <2) {cout <<"usage: "<< argv[0]<<" <csv.ext> <output_folder> "<< endl;exit(1);}string output_folder;if (argc ==3) {output_folder = string(argv[2]);}//读取你的CSV文件路径.string fn_csv = string(argv[1]);// 2个容器来存放图像数据和对应的标签vector<Mat> images;vector<int> labels;// 读取数据. 如果文件不合法就会出错// 输入的文件名已经有了.try {read_csv(fn_csv, images, labels);} catch (cv::Exception& e) {cerr <<"Error opening file ""<< fn_csv <<"".

qt-win-opensource是什么软件啊?

Qt是诺基亚开发的一个跨平台的C++图形用户界面应用程序框架。它提供给应用程序开发者建立艺术级的图形用户界面所需的所用功能。Qt是完全面向对象的,很容易扩展,并且允许真正地组件编程。自从1996年早些时候,Qt进入商业领域,它已经成为全世界范围内数千种成功的应用程序的基础。Qt也是流行的Linux桌面环境KDE 的基础。 基本上,Qt 同 X Window 上的 Motif,Openwin,GTK 等图形界 面库和 Windows 平台上的 MFC,OWL,VCL,ATL 是同类型的东西,但Qt具有优良的跨平台特性、面向对象 、丰富的API、大量的开发文档等优点。

OpenGL底层是靠xwindow吗?xwindows是显卡驱动?

应该这样理解吧,驱动是最底层的,上面一层是X-window,然后再是OpenGL! X-Window系统并不是一个软件,而是一个协议,这个协议定义一个系统成品所必需具备的功能(就如同TCP/IP,属于更底层的协议)。 然后OpenGL又是图形程序的接口,可以方便其他程序调用图形库,就是位于更上层面的接口, 我们可以这样理解,OpenGL是其他应用程序的接口,然后OpenGL需要链接到X-window,通过X-window调用底层的显卡驱动调用显卡!

DirectX和OpenGL比较?和显卡有什么关系吗?

DirectX是事实上的标准,游戏领域的主流,OpenGL则较多应用于工业领域。显卡都能支持这两个接口标准,显卡不支持,程序使用了也无法运行。

fail safe open 阀,是什么意思?

只听说过fail open阀门,不知道是不是一样的。就是指阀门控制系统出现问题后,会自动打开,相反的是fail close,自动关闭的。是从系统完全性考虑的。

小学五年级作文school open day

On Tuesday, we Wen Yuan primary school held a "parents open day" activities.This day, the whole class parents have come, looking at so many parents, I am excited and nervous, thinking in the heart: "How to do? How to do? Usually I didn"t love to speak, this time I must overcome their own, do well to mother!"The bell rang, I was nervous, heart to the throat eyes. The teacher asked us: "what is this group of numbers you find?" I suddenly have a brain wave, this is not very easy to do! I bravely raised his hand, the teacher invited me, I easily answered: "dividend multiplied by 6, the dividend unchanged,the quotient multiplied by 6." The teacher smiled and said to me: "good, who can say?"

open the window

是这个吗?“My aunt will be down presently, Mr. Nuttel,” said a very self-possessed young lady of fifteen; “in the meantime you must try and put up with me.” Privately Framton Nuttel doubted more than ever whether these formal visits on a succession of total strangers would do much towards helping the nerve cure which he was supposed to be undergoing. “I know how it will be,” his sister had said when he was preparing to migrate to this rural retreat; “you will bury yourself down there and not speak to a living soul, and your nerves will be worse than ever from moping. I shall just give you letters of introduction to all the people I know there. Some of them, as far as I can remember, were quite nice.” Framton wondered whether Mrs. Sappleton, the lady to whom he was presenting one of the letters of introduction came into the nice division. “Do you know many of the people round here?” asked the niece, when she judged that they had had sufficient silent communion. “Hardly a soul,” said Framton. “My sister was staying here, at the rectory, you know, some four years ago, and she gave me letters of introduction to some of the people here.” He made the last statement in a tone of distinct regret. “Then you know practically nothing about my aunt?” pursued the self-possessed young lady. “Only her name and address,” admitted the caller. He was wondering whether Mrs. Sappleton was in the married or widowed state. An undefinable something about the room seemed to suggest masculine habitation. “Her great tragedy happened just three years ago,” said the child; “that would be since your sister"s time.” “Her tragedy?” asked Framton; somehow in this restful country spot tragedies seemed out of place. “You may wonder why we keep that window wide open on an October afternoon,” said the niece, indicating a large French window that opened on to a lawn. “It is quite warm for the time of the year,” said Framton; “but has that window got anything to do with the tragedy?” “Out through that window, three years ago to a day, her husband and her two young brothers went off for their day"s shooting. They never came back. In crossing the moor to their favourite snipe-shooting ground they were all three engulfed in a treacherous piece of bog. Poor aunt always thinks that they will come back someday, they and the little brown spaniel that was lost with them, and walk in at that window just as they used to do. Poor dear aunt, she has often told me how they went out, her husband with his white waterproof coat over his arm, and Ronnie, her youngest brother, singing ‘Bertie, why do you bound?" as he always did to tease her, because she said it got on her nerves. Do you know, sometimes on still, quiet evenings like this, I almost get a creepy feeling that they will all walk in through that window” She broke off with a little shudder. It was a relief to Framton when the aunt bustled into the room with a whirl of apologies for being late in making her appearance. “I hope Vera has been amusing you?” she said. “She has been very interesting,” said Framton. “I hope you don"t mind the open window,” said Mrs. Sappleton briskly; “my husband and brothers will be home directly from shooting, and they always come in this way. They"ve been out for snipe in the marshes today, so they"ll make a fine mess over my poor carpets. So like you menfolk, isn"t it?” She rattled on cheerfully about the shooting and the scarcity of birds, and the prospects for duck in the winter. Framton was conscious that his hostess was giving him only a fragment of her attention, and her eyes were constantly straying past him to the open window and the lawn beyond. It was certainly an unfortunate coincidence that he should have paid his visit on this tragic anniversary. “The doctors agree in ordering me complete rest, an absence of mental excitement, and avoidance of anything in the nature of violent physical exercise,” announced Framton. “No?” said Mrs. Sappleton, in a voice which only replaced a yawn at the last moment. Then she suddenly brightened into alert attention- but not to what Framton was saying. “Here they are at last!” she cried. “Just in time for tea, and don"t they look as if they were muddy up to the eyes!” Framton shivered slightly and turned towards the niece with a look intended to convey sympathetic comprehension. The child was staring out through the open window with a dazed horror in her eyes. In a chill shock of nameless fear Framton swung round in his seat and looked in the same direction. In the deepening twilight three figures were walking across the lawn towards the window, they all carried guns under their arms, and one of them was additionally burdened with a white coat hung over his shoulders. A tired brown spaniel kept close at their heels. Noiselessly they neared the house, and then a hoarse young voice chanted out of the dusk: “I said, Bertie, why do you bound?” Framton grabbed wildly at his stick and hat; the hall door, the gravel drive, and the front gate were dimly noted stages in his headlong retreat. A cyclist coming along the road had to run into the hedge to avoid imminent collision. “Here we are, my dear,” said the bearer of the white mackintosh, coming in through the window, “fairly muddy, but most of it"s dry. Who was that who bolted out as we came up?” “A most extraordinary man, a Mr. Nuttel,” said Mrs. Sappleton; “could only talk about his illnesses, and dashed off without a word of goodbye or apology when you arrived. One would think he had seen a ghost.” “I expect it was the spaniel,” said the niece calmly; “he told me he had a horror of dogs. He was once hunted into a cemetery somewhere on the banks of the Ganges by a pack of pariah dogs, and had to spend the night in a newly dug grave with the creatures snarling and grinning and foaming just above him. Enough to make anyone lose their nerve.” Romance at short notice was her speciality. 【参考译文】敞开的窗户“纳托先生,我姑妈很快就会下来”,说话人是一位十五岁的年轻小姐,看上去沉着自信,“现在我来陪您,请多包涵。” 弗雷顿·纳托目前需要接受神经衰弱的治疗,可是一个接着一个的拜访这样完全陌生的人真的会对他的神经有什么帮助吗?他现在比以往任何时候都更加怀疑这一点。 当时他正收拾行装准备来乡下静居,姐姐对他说:“我知道最后会是什么样子!到了那里你会把自己封闭起来,不跟任何人说一句话,而你的神经会因为抑郁不乐而变得更加糟糕。我还是要写一些引见信,把你介绍给那里所有我认识的人,在我的印象中,有些人还是很和善的。” 弗雷顿现在就要把这样一封引见信交给赛普顿夫人,不知道这位夫人是不是属于和善之流。 “您在这里认识很多人吗?”那位小姐开口问道,因为她发现他们这样沉默的交流时间过长了。 “几乎一个人都不认识,”弗雷顿答道,“四年前我的姐姐在这里住过一段时间,你也许知道,在教区长的家里,是她写的引见信让我认识这里的人。” 他说最后一句话时,语气中透露出说不出的后悔。 “那么您实际上对我姑妈是一无所知了?”年轻的小姐继续问道。 “只知道她的名字和地址,”来客承认,同时他又在暗自考虑,这位赛普顿夫人的丈夫是否还健在,因为房间里有些说不清的迹象表明这里是有男人居住的。 “三年前她的家里发生了一场悲剧,”那孩子接着说,“当时您的姐姐应该已经离开这里了。” “悲剧?”弗雷顿觉得有些不可思议,不知为什么他觉得在这样的乡村静地是不会发生什么悲剧的。 “也许您会奇怪,为什么十月份的下午我们会将窗户大敞着,”那位小姐用手指着那扇宽敞的法式落地窗说。窗外是一片草坪。 “今年的十月天气不是很凉,”弗雷顿回答,“不过你的意思是说,这扇窗户跟那场悲剧有什么关系吗?” “三年前的今天,她的丈夫和两个弟弟,就是穿过那扇窗户去打猎,但是一去无返。他们当时要去那块最适合猎射沙锥鸟的地方,但是在穿过野地的时候,三个人意想不到的全部陷进沼泽里。可怜的姑妈总是相信他们有一天会回来,他们三个,还有那条跟他们一块儿失踪的西班牙猎狗,会像从前一样从那扇窗户走进来。可怜的,亲爱的姑妈,她总是跟我提起当时他们出门的情景,她的丈夫胳膊上搭着一件白色雨衣,她最小的弟弟,罗尼,唱着“伯蒂,你为什么又蹦又跳?”“因为这首歌会让她心烦意乱,所以他就经常唱这个调子打趣她。你知道吗,在这样安静的夜晚,我有时也会觉得他们会从那扇窗子走进来,这种感觉让我浑身发怵。” 讲到这里,她停了下来,打了个寒颤。这时,那位姑妈匆匆走进房间,让弗雷顿松了一口气,她一进屋就不停的道歉说自己这么迟才下楼来。 “维拉没有让您觉得无聊吧?”她问道。 “她是位很有趣的小姐。”弗雷顿回答。 “希望您不会介意我把窗户开着,”赛普顿夫人轻快的说,“我丈夫和弟弟打猎以后回家,总是从这边进来。他们今天去沼泽地打沙锥鸟,回来的时候肯定会把我的地毯弄得脏兮兮的。男人都是这样子,对吧?” 接着她又饶有兴趣喋喋不休地谈起打猎,最近树林里面鸟不多,以及冬天会有鸭子等等。在弗雷顿看来,没什么比这更可怕的了。弗雷顿意识到这位女主人大部分的注意力并不在他的身上,她的眼光不断的绕过他,朝那扇开着的窗和窗外的草坪望去。他竟然会在这个悲剧发生三周年的日子拜访这位夫人,真是个不幸的巧合! “医生们一致认为我应该彻底休息,避免任何心理刺激,和任何形式的剧烈体力运动,”弗雷顿大声说道。 “是吗?”赛普顿夫人回答,声音听上去明明就是及时的盖住了一个哈欠。突然,她精神一振,脸上神采焕发,但并不是因为弗雷顿说的话。 “他们终于回来啦!”她大声说,“正好赶上下午茶。他们看上去简直从头脏到了脚!” 弗雷顿轻轻打了个寒颤,目光朝向维拉,那位侄女儿,望去,脸上的表情想表示他的理解和同情。但是那孩子正用惊呆了的目光直直的盯着那扇敞开的窗。一阵莫名的恐惧像冷气一样袭来,弗雷顿在椅子上迅速的转过身,朝同一个方向望去。 在慢慢变深的夜色中,有三个人正穿过草坪朝窗户走来:三个人胳膊上都挎着枪,其中一个人肩上还披了一件白色的外套,一条疲惫的棕色西班牙猎犬紧跟在他们脚边。他们悄无声息,离房子越来越近,接着一个年轻嘶哑的声音在夜色中唱道:“我说,伯蒂,你为什么又蹦又跳?” 弗雷顿不顾一切的抓起自己的手杖和帽子,在他没命向外奔逃的过程中,大厅的门、石子路的车道和庄园的大门,统统没有注意到。路上一位骑自行车的人为了避开他,竟然撞到了路旁的篱笆上。 “我们回来了,亲爱的,”那位身披白色雨衣的男人一边穿过窗子走进房间,一边说道,“浑身都是泥,还好衣服没怎么弄湿。刚才有个人看见我们走过来,就匆忙离开了,是谁呀?”“一位十分不可思议的人,叫什么纳托先生,”赛普顿夫人说,“张口闭口就只知道说他的病情。看见你们回来了竟然连一句告辞或者抱歉的话也不说,转身就走,不知道的还以为看见鬼了呢。” “我想可能是因为那条猎狗吧,”她的侄女儿不动声色的说,“他刚才对我说他非常怕狗,有一次他被一群流浪狗一直追赶到了恒河岸上的某个公墓里,实在没办法只好在一个新挖的墓穴里呆了一晚上,那些可怕的野狗就在他的头顶上龇牙咧嘴的咆哮,换成是谁,魂儿也得被吓飞了。” 不做准备就编故事是这位小姐的拿手好戏。

and可以连接祈使句吗,比如说open the window and close the door

可以,没什么特别的.只是如果动作的单词都一样,可以用并列主语句 祈使句+and后面加的句子为一般将来时,祈使句表条件,第二这也符合条件状语从句中“主将从现”的规则 祈使句(表条件)+ and +主句(表结果) (1)、祈使句(表条件)+ or else/or/otherwise + 主句(表结果)…… “否则……,要不然……” (2)、祈使句(表条件)+ and +主句(表结果) [例句] Hurry up,or you"ll be late for class. Please call me up before you come,otherwise/or else/or we might be out. 你来之前打个电话,否则,我们也许会出去. Think it over and you will find the answer. Give him an inch and he will take a mile.得寸进尺. Work hard and you will make progress every day.好好学习,天天向上. 要了解“祈使句 + and + 陈述句”句型的三种变化形式   1. “祈使句 + 破折号 + 陈述句”   Try some of this juice—perhaps you"ll like it.(2000年京皖春招)   尝尝这种果汁,也许你会喜欢的.   2. “名词词组 + and + 陈述句”   名词词组中通常含有more,another,further,earlier等词.   It is really very dangerous. One more step,and the baby will fall into the well.   真危险.再多迈一步,这个小孩儿就掉进井里了.   Another £500,and I could buy a car.   假如我再有500镑,就能买辆小汽车了.   One step further and you"ll lost.   再多走一步,你就会迷失方向了.   A few minutes earlier,and I could have seen the famous scientist.   要是我早来几分钟,就能见到那位著名的科学家了.   3. “祈使句 + or + 陈述句”   or表示“否则”、“要不然的话”,or可用or else或otherwise替换,从反面来预测结果.   Take the chance,or you will regret it.   抓住机会吧,否则你会遗憾的.   Watch your step,or else you might fall into the water.   留神脚下,不然你会掉进水里的.   Do as you"re told,otherwise you"ll be in trouble.   叫你怎么做就怎么做,否则你会有麻烦的.要使用好此句型,要注意以下两个问题:   1.当陈述句是一般将来时或一般现在时的时候,祈使句是真实条件句.例如:   Follow the advice of the doctor,and you"ll be well very soon.   解析:陈述句谓语部分为一般将来时,所以祈使句表示真实条件句(If you follow the advice of the doctor).   Work hard,and you can make rapid progress in your study.   解析:陈述句谓语部分为一般现在时,所以祈使句表示真实条件句(If you work hard).   2.当陈述句的谓语动词是would / should / could / might + 动词原形或完成体时,祈使句表示非真实条件句.例如:   Pass my house and you might return the book you borrowed.   解析:陈述句谓语部分为might return,所以祈使句表示非真实条件句(If you should pass my house).   Come tomorrow and I would tell you everything.   解析:陈述句谓语部分为would tell,所以祈使句表示非真实条件句(If you should come tomorrow).

It is the Open House Day.

Open house day 建筑开放日这是一个伦敦的传统节日。Open house day 由来已久 。每年9月的一个周六周日,你将有机会免费进入伦敦超过5400多座著名的大楼中一探究竟,并了解那些保存完好的建筑秘密。市内的很多平日不允许公众进入的建筑,此时都会对游客开放。

怎么开Open House?

Open House通常是在周六或周日下午举办。事前卖方经纪人会通过插牌子,在当地报纸及MLS系统中作广告等方式进行宣传。界时卖方经纪人则会在卖主家中展示房屋。对房子感兴趣的人们,无论有无经纪人陪伴,均可扣门而入, 参观房子,并向卖方经纪人提出各种问题。房多多open house都是由卖房代理人来策划和执行,以线上直播+线下参观的模式,打造开放式卖场的看房场景,为业主节省经纪人和客户多次上门看房的时间,提升看房效率,帮助业主快速卖房。

open house是什么意思?

在外国卖房推销过程中, Open House 是最常用的方法之一。Open House通常是在周六或周日下午举办。事前卖方经纪人会通过插牌子,在当地报纸及MLS系统中作广告等方式进行宣传。界时卖方经纪人则会在卖主家中展示房屋。对房子感兴趣的人们,无论有无经纪人陪伴,均可扣门而入, 参观房 子,并向卖方经纪人提出各种问题。对买主来说,参观Open House是一个学习过程,如能与其经纪人切搓,则可对当地房屋市场有进一步了解。对卖主来说,看房人越多,房子售出的可能性越大。卖主还可以迅速地得 到潜在买主的反馈,有助于及时调整推销策略。Open House最大缺点是许多看房的人并非是迫切需要买房的人,而只是“感兴趣”。很多情况下,是周围邻居想来了解一下屋主有何家俱, 及如何摆设,又不好直说,便说是为亲戚朋友来看房。另外,住在同一社区内,打算在近期卖房的人也会趁机来“摸摸底”,比较一下房价。这些人会浪费卖主及卖方经纪人很多时间和精力。如果看房的人多,但事后又没有满意的合同,这会给卖方带来一定焦虑

python open语法中打开文件时指定解码格式为什么用的是encoding,encode不是编码的意思吗?

第一个问题, encoding是通用的说法,不一定单指编码,因为open这个函数可以打开读文件,也可以写文件第二个问题,可以这么说,其实更倾向于说是用的bytes,具体实在有点复杂没法给你讲解,好在python3处理比较好了

opening soon ! opening的词性是什么?

没必要这样计较. 可以理解为时态, 也可以理解为动名词,没什么差别.不用open soon的原因:opening soon, 首先前调open 的状态, 另外给人一种更快的感觉, 说明准备工作正在进行中.典型的例子还有, 比如电影在拍摄中,即将上演."coming soon"

能刷OpenWrt的千兆口的路由器最便宜的是哪款

openwrt系统的路由器,只有改装的二手机性价比最高,如华为hg255D,水星的MW155,MW310R, TL-WR841N 等等,其中华为的hg255D可玩性最强,又是300M无线路由器,价格在45~90元之间,可以选择,如果想要带机量大,稳定的可以购买wayos系统的维盟原生路由器,它也支持多拨,不过价格较高。 如果觉得这些路由器还不满意,那就自己DIY路由器吧,我指的是软路由,只需一台X86的古董级电脑,最低配置128M内存,128M以上外存,(硬盘,CF卡,电子硬盘,带转接卡的SD卡),两张以上网卡(与接入线路数量有关),再安装如:海蜘蛛,openwrt x86, wayos x86, dd-wrt, ros等路由器软件,总有一款适合你。

怎么用OPenCV编写一个程序把24位彩色图像转换为8位彩色图像?高分悬(50)赏求高人。5月31日急用。

以下资料可能会对你有所帮助,需要自己逐步摸索,要有耐心呀!!1在图像处理中,我们经常需要将真彩色图像转换为黑白图像。严格的讲应该是灰度图,因为真正的黑白图像是二色,即只有纯黑,纯白二色。开始之前,我们先简单补充一下计算机中图像的表示原理。计算机中的图像大致可以分成两类:位图和矢量图。位图可以视为一个二维的网格,整个图像就是由很多个点组成的,点的个数等于位图的宽乘以高。每个点被称为一个像素点,每个像素点有确定的颜色,当很多个像素合在一起时就形成了一幅完整的图像。我们通常使用的图像大部分都是位图,如数码相机拍摄的照片,都是位图。因为位图可以完美的表示图像的细节,能较好的还原图像的原景。但位图也有缺点:第一是体积比较大,所以人们开发了很多压缩图像格式来储存位图图像,目前应用最广的是JPEG格式,在WEB上得到了广泛应用,另外还有GIF,PNG等等。第二是位图在放大时,不可避免的会出现锯齿现象,这也由位图的本质特点决定的。所以在现实中,我们还需要使用到另一种图像格式:矢量图。同位图不同,矢量图同位图的原理不同,矢量图是利用数学公式通过圆,线段等绘制出来的,所以不管如何放大都不会出现变形,但矢量图不能描述非常复杂的图像。所以矢量图都是用来描述图形图案,各种CAD软件等等都是使用矢量格式来保存文件的。在讲解颜色转换之前,我们要先对位图的颜色表示方式做一了解。位图中通常是用RGB三色方式来表示颜色的(位数很少时要使用调色板) 。所以每个像素采用不同的位数,就可以表示出不同数量的颜色。如下图所示:每像素的位数 一个像素可分配到的颜色数量 2^1 = 2^2 = 2^4 = 12^8 = 2512^16 = 65,5322^24 = 16,777,21从中我们可以看出,当使用2位色(个字节)时,我们可以得到1600多万种颜色,这已经非常丰富了,应该已接近人眼所能分辨的颜色了。现在计算机中使用最多的就是2位色,别外在GDI+中还有一种3位色,多出来的一个通道用来描述Alpha,即透明分量。2位色中个字节分别用来描述R,G,B三种颜色分量,我们看到这其中是没有亮度分量的,这是因为在RGB表示方式中,亮度也是直接可以从颜色分量中得到的,每一颜色分量值的范围都是从0到255, 某一颜色分量的值越大,就表示这一分量的亮度值越高,所以25表示最亮,0表示最暗。那么一个真彩色像素点转换为灰度图时它的亮度值应该是多少呢,首先我们想到的平均值,即将R+G+B/。但现实中我们使用的却是如下的公式:Y = 0.299R+0.587G+0.114B 这个公式通常都被称为心理学灰度公式。这里面我们看到绿色分量所占比重最大。因为科学家发现使用上述公式进行转换时所得到的灰度图最接近人眼对灰度图的感觉。因为灰度图中颜色数量一共只有25种(个字节),所以转换后的图像我们通常保存为位格式而不是2位格式,这样比较节省空间。而位图像是使用调色板方式来保存颜色的。而不是直接保存颜色值。调色板中可以保存25颜色,所以可以正好可以将25种灰度颜色保存到调色版中。代码如下:using System;using System.Collections.Generic;using System.Text;using System.Drawing;using System.Drawing.Imaging;namespace ConsoleApplication2}img.UnlockBits;bit.UnlockBits;ColorPalette palette = bit.Palette;for bit.Palette = palette;bit.Save;img.Dispose;bit.Dispose;}}} 代码中我使用了指针直接操作位图数据,同样的操作要比使用GetPixel, SetPixel快非常多。我们要感谢微软在C#中保留了这一强有力的工具。

OpenStack 和 Hadoop 的区别是什么

openstack是一个iaas云平台(云计算saas,paas,iaas中的iaas),是亚马逊aws的开源实现。OpenStack是一个开源的云计算管理平台项目,由几个主要的组件组合起来完成具体工作。OpenStack支持几乎所有类型的云环境,项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务(IaaS)的解决方案,每个服务提供API以进行集成。hadoop是一个分布式的软件架构,有分布式计算和分布式存储。Hadoop是一个由Apache基金会所开发的分布式系统基础架构。用户可以在不了解分布式底层细节的情况下,开发分布式程序。充分利用集群的威力进行高速运算和存储。Hadoop实现了一个分布式文件系统(Hadoop Distributed File System),简称HDFS。HDFS有高容错性的特点,并且设计用来部署在低廉的(low-cost)硬件上;而且它提供高吞吐量(high throughput)来访问应用程序的数据,适合那些有着超大数据集(large data set)的应用程序。HDFS放宽了(relax)POSIX的要求,可以以流的形式访问(streaming access)文件系统中的数据。Hadoop的框架最核心的设计就是:HDFS和MapReduce。HDFS为海量的数据提供了存储,则MapReduce为海量的数据提供了计算。

opengles shader 可以用for吗

Shader可以说是现代OpenGL的灵魂。这牵涉到一个历史遗留问题:GL 1.x中只有固定管线,渲染效果是固定的,而在GL 2.0中增加了可编程管线,想要什么渲染效果都可以自己往加。GL 3.0+就废弃了固定管线,也就是说不写Shader是不推荐的。不写Shader的固定管线时代早就在十多年前过去了。回到GLES中,GLES 1.0是固定管线(为了某些原因),不需要也不能写Shader;GLES 2.0+是可编程管线,必须写Shader。建议题主少走点弯路,直接上可编程管线。虽然比固定管线稍微要多做点工作,但长远来看是好的,能做出更炫的效果并充分利用GPU。退固定管线保平安。

turn on 和 open的区别

因为平时会和家里小朋友说一点点非常非常简单的口语,关于两个“打开”平时和小朋友说的最多的就是open the door 和turn on the light,其他的感觉都说得很少,所以今儿自己也度娘理一份这两则的区别,等小朋友以后自己大点了,开始英文课了,也能有自己的一个理解区分,到时候如果需要用到我的笔记,老母亲也能立马奉上 Turn on: to start using a supply of water, gas, heat, sound or electricity by turning a faucet, pressing a button, or moving a switch. 通过转动水龙头、按下按钮或移动开关开始使用水、气、热、声或电(基本涉及到这五类的“打开”都是用的turn on)。 他们俩都是同步出现的,用了turn on ,对应的就是用turn off ①开门/窗类型的东西 ②用于各种容器/或者任何有封口的东西 ③用于可以展开的东西,如书本/杂志等 ④用于身体部分 ⑤用于其他开店等 ⑥一些固定习语 他们俩都是同步出现的,用了open ,对应的关就用close 首先“开支票”肯定不是open the check。 我们说的"开支票",其实中文意思是拿出支票本并"写支票",所以对应的英语翻译应该write a check “开支票账号”的表达则是:Open checking account。 参考连接
