Abstract

In a video processing system (15), dense motion vector fields are generated representing the motion of image elements from frame to frame. One or more pixel characteristics of the pixels in the video frames are adjusted in accordance with the corresponding vectors of the dense motion vector fields. The pixel characteristics that are adjusted include color, brightness, saturation, and contrast. The pixel characteristics are adjusted in accordance with the magnitude and/or direction of the dense motion field vectors and in accordance with the acceleration of the corresponding image elements.
