分析HSI颜色空间和RGB颜色空间应用于检测彩色图像边缘时的缺点，提出一种基于数学形态学的彩色图像边缘检测算法。该算法在HSI颜色空间利用字典序给像素向量排序，然后逐对确定膨胀运算和腐蚀运算的像素，在RGB颜色空间利用这对像素计算边缘图像的像素点。实验结果表明：所提出算法检测的图像边缘轮廓清晰、连续平滑、细节丰富、边界完整、时间效率较高。
分析HSI顏色空間和RGB顏色空間應用于檢測綵色圖像邊緣時的缺點，提齣一種基于數學形態學的綵色圖像邊緣檢測算法。該算法在HSI顏色空間利用字典序給像素嚮量排序，然後逐對確定膨脹運算和腐蝕運算的像素，在RGB顏色空間利用這對像素計算邊緣圖像的像素點。實驗結果錶明：所提齣算法檢測的圖像邊緣輪廓清晰、連續平滑、細節豐富、邊界完整、時間效率較高。

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 a -ble to keep more complete outline of the color image , and it has a relatively small amount of calculation .The algorithm has better a-bility of preserving the edge details and better robustness .
