I'm trying to train an hogcascade classifier, like hogcascade_pedestrian.xml, but for head and shoulders, i have prepared .vec file with opencv_createsamples

opencv_createsamples -info positives.dat -vec vecfile.vec -num 3500 -bg negatives.dat -w 32 -h 32

All done, but when i launch opencv_traincascade with:

opencv_traincascade -data hognew -vec vecfile.vec -bg negatives.dat -mem 2048  -numStages 15 -featureType HOG -w 32 -h 32  -maxWeakCount 100

after 15 stages i have in hognew directory cascades.xml , well...but when i try it with detectmultiscale it doesn't work, program freeze, with hogcascade_pedestrian.xml it's all ok.

When i open cascade.xml and hogcascade_pedestrian.xml they are slightly different Anyone can give me an hand to understand how to train hogcascade?

Hi to all, i'm trying to understand how to use kalman filter in opencv 3.0 with python, the sample code is for old version and i don't know how to initialize kalman filter with new wrapper, anyone has a sample code?
