Sažetak
Natural, continuous tone images have a very important property of high correlation of adjacent pixels. This property is cleverly exploited in lossless image compression where, prior to the statistical modeling and entropy coding step, predictive coding as decorrelation tool is used. The use of prediction for current pixel also reduces the model cost of applied statistical model for entropy coding. Linear prediction, where predicted value is linear function of previously encoded pixels (causal template), has proven to give very good results as a decorrelation tool in lossless image compression. In this work we concetrate on adaptive linear predictors used in lossless image coding and propose a new linear prediction method.
