Hello,
I'm new with opencv and I have a problem that I don't understand.
I'm trying to generate a haarcascade to detect big truck on the road but the generating is blocked at stage 11 during the collect of negative/sample.
I Gathered 2015 positives and 6970 negatives. The size of the positives and negatives is 32 x 32.
So I used the folowing command lines on ubuntu was :
create text files for positives and negatives :
find ./negative_images -iname ".jpg" > negatives.txt find ./positive_images -iname ".jpg" > positives.txt
**I created 3500 samples (32 x 32) and maximum size because all of my pictures are 32 x 32 : perl bin/createsamples.pl positives.txt negatives.txt samples 3500 "opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 32 -w 32 -h 32"
I merged all .vec files : python ./tools/mergevec.py -v samples/ -o samples.vec
And then I trained my haar cascade with 20 stage : opencv_traincascade -data haar -vec samples.vec -bg negatives.txt -numStages 20 -minHitRate 0.999 -maxFalseAlarmRate 0.5 -numPos 2015 -numNeg 6970 -w 32 -h 32 -mode ALL -precalcValBufSize 256 -precalcIdxBufSize 256
If someone could help me to find out why the the opencv_traincascade is blocked at stage 11 it will be very grateful.
ps : I used this tools https://github.com/spmallick/opencv-haar-classifier-training I used the opencv 3.2.0 version
