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 efficient coding of images and video signals of a high dynamic range. The MMR models may include first order parameters, second order parameters, and cross-pixel parameters. The MMR models using extension parameters incorporating neighbor pixel relation are also presented. By using criteria of a minimum mean square error, closed-form solutions for prediction parameters are presented for a variety of MMR models.SELECTED DRAWING: Figure 4 |
