Description

opencv_createsamples can either create randomized samples from a single positive image or generate a vector file from multiple positive samples. It seems unable to create randomized samples from multiple positive images. For example, I have 500 positive sample images. I would like 6000 positives for training. I would like to be able to create 12 randomized images from each input image by specifying -num 6000 to createsamples. If this is done now, an error will occue on sample 501 as it reads past the end of the info.dat file.

Trevor, this is well-known limitiation of OpenCV training utility. And, unfortunately nobody is going to work on it...
