I am doing the performance.exe and I have done the haartraining.exe. So what about the describe of the files used in performance? Is that shoud like the positive describe file like "a.jpg 1 0 0 30 30" ? Or just be "a.jpg"?

If should be the former, in this describe the "0 (x), 0 (y)"and the "30 (w), 30 (h)" should be the size of postive samples used in createsample.exe? or should be the object detection file, like a target picture, "a.jpg 1 100 150 300 400" ?

If should be the latter, Why I can not detect anything shoud as a red rectangle? Actually when the latter, the performance does nothing.

And I have tried to modify the number in "a.jpg 1 0 0 30 30" to any kind of "a.jpg 1 x x xxx xxx" It can detect the object but every time the same result.

Does anyone have some experience about this?

Well it is the collection of file names only. In your case like a.jpg. The usage is as follows:

Usage: ./performance -data (classifier_directory_name) -info (collection_file_name) [-maxSizeDiff (max_size_difference = 1.500000)] [-maxPosDiff (max_position_difference = 0.300000)] [-sf (scale_factor = 1.200000)] [-ni] [-nos (number_of_stages = -1)] [-rs (roc_size = 40)] [-w (sample_width = 24)] [-h (sample_height = 24)]

Sample usage can be:

performance.exe -data haarcascade -w 20 -h 20 -info tests.txt -ni

Where tests.txt has the list of file names.
