| 摘 要： | 针对传统边缘检测算法最初只基于灰度图像,对彩色图像提取的边缘定位不准确、边缘有断点等问题,将在HSV彩色空间中对彩色图像进行了多通道边缘检测.考虑到传统边缘检测算子对图像的噪声和明暗程度比较敏感,采用相位一致和数学形态学相结合的方法对单通道图像进行边缘检测.仿真实验显示,该方法可以有效地提取彩色图像的边缘.

| Abstract: | The traditional edge detection algorithm is only applicable to grayscale images. When it is used to the extraction of a color image, the edge can not be positioned exactly and the edge breakpoints usually happen. This paper presents an algorithm for multi-channel edge detection of the color image in the HSV color space. Considering the traditional edge detection operator＇s sensitivity to the brighuness level and noise level of pictures, phase congruency and mathematical morphology method were combined in single-channel image edge detection. Simulation results show that this algorithm can effectively extract the edge of color images. |
