Abstract
This Paper Introduces a Nonstationary Model for Images and Develops an Adaptive Intrafield Dpcm Codec based Upon the Model. the Codec Attempts to Minimize the Mean‐square Coding Error at Each Sample Point in the Picture. the Quantizer in the Resulting Adaptive Codec is Found to Be Similar to that Previously Obtained from Visual Masking Considerations. Comparative Simulation Results using 256 X 256 Pixel Rasters Are Given for Two‐ and Three‐bit/pixel Versions of the Adaptive Codec, the Three‐bit/pixel Graham Codec, and Three‐bit/pixel Previous Element Dpcm. © 1979 the Bell System Technical Journal
