A Naive Bayes probabilistic model was fitted to these histograms.This model
could be applied to a new image to estimate the probability that the image belongs to any of the 9 stonefly taxa.New specimens were rejected as being nonstoneflies based on a threshold or operating point (OP) for this probability.For the results reported in this paper,we selected the OP at the equal error rate (EER; the EER OP is where the proportion of distracters rejected equals the proportion of stoneflies accepted).We estimated the OP threshold using only the training set (without distractors) by averaging over the 9 EER thresholds obtained by treating 1 stonefly taxon at a time as a distractor and using the Naive Bayes model trained on the remaining 8 taxa.
Given a new image,the system operated as follows.First,the NaIve Bayes model was evaluated,and the output probability was compared to the OP threshold.If it was less than the threshold,the image was rejected as being a nonstonefly.Otherwise,the SIFT descriptors were passed to the classifier,which assigned the image to one of the 9 stonefly taxa.
