摘要
考虑到医学彩色内窥镜图像的特殊性，用Ｋ－Ｌ变换，将经锐化处理后的彩色图像分解成３个正交彩色基Ｉ１，Ｉ２和Ｉ３，提出用Ｋｉｒｓｃｈ算子对含丰富特征的单色图Ｉ１进行边缘检测，并用Ｉ２和Ｉ３进行补偿，使获得的彩色回显图像边缘清晰，细节丰富．
Considering the specificity of the medical color endoscope image,a medical color image after sharped is decomposed as three color orthogonal feature: I 1,I 2 and I 3 in K L transformation method,and Kirsch algorithm is used to detect the edge of the monochrome image I 1 including rich information.Finally,both clarity edge and rich detail of color backdisplay image are gained if adopting I 2 and I 3 to compensate I 1 .
