Abstract
A line-based one-dimensional system and method for video and graphic compression compresses an image data block that contains image data values from one or more neighboring pixels. The system and method involves compressing an image data sample of the image data block using multiple different compression techniques to generate multiple compression results, selecting one of the compression results, and compressing a next image data sample using the multiple different compression techniques and a compression error from the selected one of the compression results.
