不同彩色空间的彩色图像边缘检测研究

边缘信息是图像处理中的一种重要信息，通常的边缘检测研究是基于灰度图像的，然而彩色图像比灰度图像包含有更加丰富的边缘信息。彩色图像的边缘检测可以在不同的彩色空间中进行，目前大多数研究集中在RGB空间中。使用基于扩展的SUSAN边缘检测算子，将彩色图像在空间中的各分量分别进行边缘检测，对结果进行综合得到彩色图像的边缘检测结果，然后采用主观评价准则对若干不同的彩色空间中（包括RGB、YUV、YIQ、YCbCr、HSV、HSI）的试验结果进行了分析比较。试验结果表明，在HSV空间进行的边缘检测具有更好的性能。

Research of Color Edge Detection in Different Color Spaces

Edge information is important in image processing.The research of edge detection is based on gray image commonly.However,more edge information can be got from color image than that from gray image.Edge detection can be done in different color spaces while the main focus nowadays is in RGB color space.The color edge detection result here is the combination of separate detection results which are got from separate dimensions in color space using extended SUSAN edge detector.An analysis and comparison of color edge detection in several different color spaces(Including RGB,YUV,YIQ,YCbCr,HSV,HIS) using objective principle is presented in the paper.The experiment result shows that the better result is from HSV space.
