| Abstract(in English) | The purpose of our research is color bleeding reduction for images and videos compressed by 4:2:0 color format. We proposed the extended joint bilateral filter which realize denoising and deblurring simultaneously and showed it's high effectiveness for artificial images. However, the filter has a problem that PSNR is not always improved at natural images. In this paper, we show the result of a study of a local adaptation technique which controls filter parameters based on our uniform region similarity measure between luma and chroma components. |
