ABSTRACT:
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 a digitized analog video signal into its piecewise linear equivalent, and then reduces the data stream by preserving only the break points. The linear segments may be as short as one pixel. After a predetermined slope length has been reached, the improved pointing technique combines length-limited points if the slopes of the corresponding linear segments are identical.
