| Abstract(in English) | This paper presents an efficient lossless compression approach for gray scale images. We divide the input image to blocks of pixels and use different scanning methods for compression. An adaptive linear prediction model is applied corresponding to the statistics of neighbor pixels obtained from each scanning. The prediction coefficients are updated during the scanning to optimize the coding accuracy. From the models built by different scanning, we select the one that minimizes the prediction error for coding. Experiment results show that our method out-performed JPEG-LS 4-5% in compression efficiency. |
