Abstract
A vertical scrolling region detector may include a motion estimator that can generate motion vectors between blocks of two or more primary frames of a mixed-mode video sequence. The detector may also include a primary frame motion analyzer that can analyze the motion vectors to detect substantially constant vertical motion of at least some of the blocks between the two or more primary frames. The presence of substantially constant vertical motion may reflect the presence of a vertical scrolling region in the mixed-mode video sequence. Moreover, the detector may also include a consecutive frame motion analyzer that can calculate differences in pixel values between lines of two or more consecutive frames in the mixed-mode video sequence. The differences in pixel values may further reflect the presence of the vertical scrolling region in the mixed-mode video sequence.
