I tried to detect object which could have different aspect ration in the positive photo.
I used the next params:
opencv_traincascade -data haarcascade -vec samples.vec -bg negative.dat -numStages 15 -minhitrate 0.99 -maxFalseAlarmRate 0.4 -numPos 797 -numNeg 933 -w 15 -h 30 -mode ALL -precalcValBufSize 2048 -precalcIdxBufSize 2048
So, aspect ratio is 1:2 in the image pattern.
And when I use a generated cascade.xml I can detect an object in the pictures only with the similar aspect ratio. But some photos contains objects with 2:3 or even 1:1 ratio.
How can I detect these objects?
