【Abstract】 By analyzing the weaknesses of the color space of RGB and HSI,the paper puts forward a color image edge detection algorithm based on mathematical morphology.The algorithm realizes lexicographical order for the pixels in the HSI space,and then to define operations of dilation and erosion.By calculating distance between images dilated and eroded from a color image,the edge information of color image is obtained.Experimental results indicate that edge detection which detected by the proposed method is able to keep more complete outline of the color image,and it has a relatively small amount of calculation.The algorithm has better ability of preserving the edge details and better robustness.更多还原
