LINE-BASED COMPRESSION FOR DIGITAL IMAGE DATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 18464433 titled 'LINE-BASED COMPRESSION FOR DIGITAL IMAGE DATA
Simplified Explanation
The abstract describes a method for compressing digital image data using variable length entropy codes and spatial prediction. The method involves selecting an entropy code from a set of codes, using spatial prediction to calculate a pixel predictor and residual for each pixel in a line of pixels, and encoding the pixel residual using either the selected entropy code or run mode encoding.

Original Abstract Submitted
A method of compressing digital image data is provided that includes selecting an entropy code for encoding a line of pixels in the digital image data, wherein the entropy code is selected from a plurality of variable length entropy codes, using spatial prediction to compute a pixel predictor and a pixel residual for a pixel in the line of pixels, and selectively encoding the pixel residual using one of the entropy code or run mode encoding.
