I have a background modeled image. and i try to perform background subtraction for the incoming frames in the video, then apply a threshold to extract a foreground object. When i apply a threshold most of the white intensity pixels has lower values falls in the background pixels, which is supposed to be a foreground. this works good for other coloured intensity pixels. As decreasing the threshold value, more of the background falls in the foreground region.
I am new to background subtraction technique. Is there any advanced technique, any solution to overcome my problem will help me more forward. Expecting some positive reply from experts.
