发明名称 Reduced representations of video sequences
摘要 A system that represents a video sequence comprising plurality of video clips as a number of images. The plurality of video clips is represented as a reduced representation of video images. A video clip is represented as a keyframe, wherein multiple keyframes may then be arranged according to chronological order. All or only a representative portion of the video clips can be represented as keyframes. The size of the keyframe may be configured to represent the length or importance of the video clip. The keyframe may depict an entire frame of a video clip, or a region of meaningful information within a frame of a video clip. Multiple keyframes may be arranged in a two dimensional array, in an S-shaped curve, or some other pattern. The keyframes may depict motion of an object occurring over time in the video clip by configuring groups of pixels in the key frame. Configuring groups of pixels may include colorizing pixel groups and depicting pixel groups at a semi-transparent level according to the number of frames between the keyframe and the frame containing the object in motion.
