| Abstract(in English) | Lossless image compression is needed in the areas of medical imaging, high-definition image analysis and archives for art. In this paper, we propose the optimization method of reference pixel arrangement in the lossless coding for HDTV still image. In our method, an image is divided into small blocks and classified into some classes each of which corresponds to one MMSE linear predictor. After the fast optimization of block classification with a small number of reference pixels, we optimize the number and the arrangement of reference pixels based on variable selection technique which uses F-statistic in multiple linear regression analysis. As a result of experiments, it is confirmed that our method achieves higher compression ratio and faster processing speed, than conventional one. |
