摘要：The invention provides a method, and related apparatus, for improved
compression of video images by determining optimum compression points using pixel-to-pixel slope comparison techniques and relaxable length limits. The method converts adigitized analog video signal into its piecewise linear equivalent, and then reduces thedata stream by preserving only the break points. The linear segments may be as short asone pixel. After a predetermined slope length has been reached, the improved pointingtechnique combines length-limited points if the slopes of the corresponding linearsegments are identical.
