Description

Hi,

I run the peopledetect twice with the same input image. However, the score of detected objects is different although the boundingboxes are the same. Are there any memory leaks or bugs in hog.cpp? I upload 2 screenshots--.

My OpenCV version is 2.3.1. I do not know if this bug is fixed for further versions.

long long yu, I wasn't able to reproduce your failure in OpenCV 2.4.3. detectMultiScale return the same weights in different calls.
So could you try the latest OpenCV version and check if problem still exists?
Or just attach here your code that causes problems, I'll try to figure out where problem is.
