I am using the traincascade.exe from OpenCV 3.1 and trying to speed up the processing time.
I set the precalcValBufSize and the precalcIdxBufSize both to 512 and then both to 2048. However the run time to create the classifier did not change from when no value was specified for these values (using default value of 1024), is there a problem with precalcValBufSize and the precalcIdxBufSize in OpenCV 3.1?
