    • A method for improving quality of an image includes storing feature quantity candidates each having a luminance component for improving of quality of a first image, dividing the first image into blocks with an overlapping region formed between adjacent first and second blocks, assigning first and second feature quantity candidates selected from the feature quantity candidates of the storage to the first and second blocks, respectively, calculating an energy expressing each similarity between first and second luminance patterns of the first and second feature quantity candidates in the overlapping region, selecting one first feature quantity and one second feature quantity from the first and second feature quantity candidates, using the energy, and improving qualities of the first and second blocks using the first and second feature quantities to generate a second image.
    • 一种用于提高图像质量的方法包括存储具有用于提高第一图像的质量的亮度分量的特征量候选,将第一图像划分为具有形成在相邻第一和第二块之间的重叠区域的块,分配第一和第二特征 从所述存储的特征量候补分别选择到所述第一和第二块的数量候选,计算表示所述重叠区域中的所述第一和第二特征量候选的第一和第二亮度图案之间的每个相似度的能量,选择一个第一特征量 以及来自第一和第二特征量候选的一个第二特征量,使用能量,并且使用第一和第二特征量来改善第一和第二块的质量以产生第二图像。
