摘要
边缘检测对于彩色图像的处理是一个难题,文章提出了一种基于数学形态学的彩色图像边缘检测的算法,其思想是:对图像用一定的结构元素操作后,与原图像相减。对彩色图像进行腐蚀和膨胀操作的数学形态学算子是本文算法的关键。实验结果表明,本算法能较好地检测出彩色图像的边缘。在对色调的保护上明显优于Sobel和Prewitt算子扩展法,能较好的检测出图像中存在的特征与背景变换缓慢的边缘信息。
Edge detection is a difficult problem in the processing of colored image,In this paper, a new colored edge detection algorithm based on mathematical morphology is proposed. The thought is after being operated by certain structural element, the image is subtracted with the original one. The key of the algorithm is using morphological operator to corrode and inflate the image .The experimental result indicated that, the edge of the colored image can be well detected by using the algorithm, and the algorithm is superior to the Sobel and the Prewitt operator expanding methods in the protection to the tone, it can also examine the edge information of characteristic and background slowly transforming of image.
