YCb Cr是一种有效的彩色图像描述格式 ,但它引入了人工彩色 .给出一种当图像再现时部分去除人工彩色的方法 ,以此增强二次抽样的图像 .增强的基本原理是根据亮度信息和色度信息之间存在高度的相关性 ,用高分辨率亮度信息制导重建高分辨率色度信息 .
YCb Cr is an effective color image description format, but it introduces artificial colors, giving a method of partially removing artificial colors when the image is reproduced, thereby enhancing the subsampled image.The basic principle of enhancement is based on the brightness There is a high degree of correlation between information and colorimetric information, which is guided by high-resolution luminance information to reconstruct high-resolution colorimetric information.
