| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this talk, the lossless image/video coding method that is proposed by the author is introduced. The proposed method estimates the probability distribution of pixel value by using the Gaussian mixture model for pixel-by-pixel. Then, each pixel value is coded by multiple-value arithmetic coding. Each Gaussian is generated by adaptive prediction and example search. The adaptive prediction is using information neighboring a target pixel. On the other hand, the example search is using non-neighboring information. The shape of the probability distribution can be controlled by a few parameters. To improve coding performance, those parameters are optimized to minimize entropy by a non-linear optimization method. | |
