Abstract
Techniques are provided for detection and location of active display regions in videos with static borders. A methodology implementing the techniques according to an embodiment includes extracting features from rows and columns of pixels of a video frame. The features are based on horizontal gradient runs (HGRs) and vertical gradient runs (VGRs). The method also includes detecting one or more static regions of the frame, based on a comparison of differences between the features of the current video frame and features extracted from a previous video frame. The method further includes detecting one or more boundaries of the static regions based on a location of a maximum value of one of the features within the static region, if the maximum value is greater than a boundary detection threshold value. Determination of the active region in the current video frame is based on exclusion of the detected static regions.
