摘要
主要根据灰度图像的边缘检测算法思想 ,借助空域微分算子 ,通过卷积提出了基于边缘的两种彩色图像分割算法。一种是将彩色图像转化为灰度图像 ,再进行分割处理 ;另一种是在三基色空间分别进行分割 ,再加以合成。同时文章采用了迭代阈值设定、区域生长、空间滤波等方法 ,有效改善了分割结果。
According to the algorithm idea of edge detection of gray scale images,with the aid of differential operator and through convolution,two algorithms(based one dge)of segmentingcolor images are put forward.The one is to convert the color image into grey scale image,the segmentation is followed.The other is to segment the color image separately in RGB color space,then composition is followed.The methods of setting of iterative threshold value,regiongrowth and space filter are adopted in the paper.
