After these initial experiments, we tested the best network on a larger set of model
projections taken at 1o increments in azimuth and elevation, totaling 41400 images (180 x 46 x 5).
The average recall and precision were 87.3%. Table 1 shows the confusion matrix of counts. Here
“Overall Recall” refers to accuracy within the row and “Overall Precision” refers to accuracy
within the column. As extra confirmation, we also ran the system on the 25 real infrared images
and got an average recall of 68% and precision of 72%. We saw no evidence of overtraining at
this size of a training corpus, but did see it when angle increments were further decreased.
