First, a modified block representation approach is used to classify each block of the current video frame into one of the four categories, namely, “background,” “still object,” “illumination change,” and “moving object.” Then, a new background updating scheme is developed, in which...
The video streams of backgrounds are frequently influenced by the background changes (e.g. illumination changes and changes due to adding or removing parts of the background). Further more, the quality of the foreground and the segmented image of hand gesture severely drops. We propose a novel method, which is based on difference background image between consecutive video frames, of using the '3sigma...
