Graphical representation of motion in still video images
First Claim
1. A method of producing a graphical representation of motion in a still picture comprising selecting a key frame from a sequence of video frames representing object motion, detecting the motion of at least one object represented by said sequence of video frames, and rendering a graphic representation of the motion of said object superimposed upon said key frame.

Abstract
In a system for processing video to represent motion in still images, the motion of objects in the video is detected by a video processor which generates dense motion vector fields to identify moving objects in a selected video frame. The video processor adds speedlines to the selected frame, contour repetition to the selected frame, or image repetition to the selected frame to represent the motion of the objects in the selected frame.

- 11. An apparatus for producing a still picture with graphical representation of object motion comprising a source of a video comprising a sequence of video frames representing object motion, a video data processor connected to receive said video frames and operable to detect from said video frames the motion of objects represented by said video at a key frame of said video and to overlay on said key frame a graphical representation of the object motion detected.
