A new model regarding the difference values of a DPCM coder as a composite source is presented. It can provide a decrease in the entropy of prediction errors and is especially useful in lossless coding and distortion limited compression. Application to image coding demonstrates its effectiveness.

Inspec keywords: image coding; coding errors; differential pulse code modulation; source coding; data compression; entropy

Other keywords: distortion limited compression; image coding; entropy; lossless coding; prediction errors; DPCM coder; composite source model

Subjects: Optical information, image and video signal processing; Codes
