彩色图像边沿色彩补偿检测方法

针对彩色图像边沿提取处理时，不能套用比较简单而成熟的黑白图像处理方法，本文提出的应用ＯＨＴＡＫ－Ｌ变换，将通常的（Ｒ，Ｇ，Ｂ）彩色空间转换为彩色特征（Ｉ２、Ｉ２、Ｉ３）空间，然后在（Ｉ２，Ｉ２，Ｉ３）空间进行灰度边缘分析，并以Ｉ１为主进行色彩边缘补偿，即可得到清晰且细致的边沿轮廓图。与彩色图像直接边沿提取及改变调色板变为黑白灰度图像后进行边沿提取比较，效果令是满意的。

COLOR IMAGE EDGE DETECTIONS USING THE BASIC COLOR COMPENSATION

As is well known, we cannot directly apply the gray image processing techniques to color image processing. A new method described in the paper includes applying the Ohta's K - L transformation , turning the common used ( R, G, B) color space into the new color space (I1,I2,I3), and extracting the edges in the new space. In the end, the mergence of the three-outline image, a distinct and exquisite oudine will be present. Compared with other methods, its effect is good.
