增强YCbCr图像色度信息的一种方法

A Method of Enhancing YCbCr Chrominance Information

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 .

YCbCr is an effective descriptive format of color image.However,it introduces visible artificial color.A method for partially eliminating the artifacts is presented. The subsampled images will be enhanced by the method when the images is reproduced.Because high degree of correlation exists between the primaries of the chrominace and the luminance,the principle of the method presented is to reconstruct the high resolution chrominance information using the high resolution luminance information to guide the enhancement.
