PIXEL-BASED DIRECTIONAL PREDICTION PATTERNS FOR DIGITAL CODING OF IMAGES.

摘要

Pixel-based prediction patterns for YUV and RGB data for compression of digital images are described herein. The prediction patterns contain eight directional predictions (right right up, right up, right up up, up, left up up, left up, left left up and left) and one non-directional (DC) prediction. Prediction for each color component is performed using samples only from the same color component but at a different position. DC prediction corresponds to averaging 4 or 8 pixels in the previous line of the current sample.
