MULTIPLE COLOR CHANNEL MULTIPLE REGRESSION PREDICTOR

摘要

PROBLEM TO BE SOLVED: To provide a multiple color channel multiple regression predictor.SOLUTION: Inter-color image prediction is based on multi-channel multiple regression (MMR) models. Image prediction is applied to the efficient coding of images and video signals of a high dynamic range. MMR models may include first order parameters, second order parameters, and cross-pixel parameters. MMR models using extension parameters incorporating neighbor pixel relations are also presented. Using minimum mean square error criteria, closed-form solutions for prediction parameters are presented for a variety of MMR models.
