MRP (2007)Minimum-Rate PredictorsCoding rates (bits/byte)• 從前 :the linear prediction coefficients aredetermined so as to minimize the mean squaredprediction errors.• 缺失 :the goal of lossless image coding is to reducethe coding rate, minimizing the mean squaredprediction errors does not yield the best results.• 解法 :to formulate the amount of information on theprediction errors and design the predictors so as tominimize that value.Ichiro Matsuda, Hirofumi Mori, Joji Maeda, Susumu Itoh: "Design and Evaluation of Minimum-Rate Predictors forLossless Image Coding", Systems and Computers in Japan, Vol.38, No.5, pp.90-98, (May 2007).
