| Abstract(in English) | Lossless image compression is needed in the areas of medical imaging, high-definition image analysis and archives for art. Therefore, this paper presents a lossless image compression method for one frame of high-definition television (HDTV). We apply an adaptive liner prediction, and then the sequence of prediction errors is encoded by entropy coding. We divide an image into small blocks and classify them into some classes each of which corresponds to one MMSE linear predictor. Repeating classification of the blocks and rebuilding of the predictors until the prediction MSE converges, we get the optimal set of linear predictors for given image. In this paper, we consider the influence of the context length and the number of the linear predictors on compression ratio and processing time. |
