基于圖像修復(fù)技術(shù)的壓縮方法的研究
Research of Image Compression Based on Image Inpainting

摘要: 通過(guò)對(duì)塊狀缺損圖像修復(fù)技術(shù)的研究，提出一種改進(jìn)的紋理合成修復(fù)算法。繼而依據(jù)粗糙度的分析對(duì)圖像塊進(jìn)行分類，根據(jù)修復(fù)算法特性人為丟棄部分圖像塊，并結(jié)合JPEG算法進(jìn)行壓縮編碼。在相近的視覺(jué)效果下，可以使圖像壓縮率得到顯著的提高。

Abstract: An optimized approach based on texture synthesis for filling-in blocks of missing data is presented in this paper. According to coarseness analysis and the character of inpainting algorithm, parts of image blocks would be dropped purposively. And then, this method is applied to the second-time image compression along with other compression algorithms such as JPEG, and the compression ratio is highly improved. -
