| 摘 要： | 基于云模型和模糊集理论。提出了一种新的边缘检测方法．该方法根据图像灰度。借助区域生长算法产生对象云；通过云运算生成边界云并构建模糊隶属带。进而在条件概率和模糊划分熵的基础上。根据最大模糊熵原则确定最优阈值，对图像模糊边界进行提取．试验结果表明。该算法能保留大量低灰度信息。可以获得较好的枪涮特栗． |

| Abstract: | Based on the cloud model and the fuzzy set theory, a new edge detection method was proposed. Firstly, with this method, object clouds are generated using the region growth algorithm on the basis of the gray level of images. Secondly, boundary clouds and fuzzy membership regions for two or more clouds are obtained based on Boolean calculation. Thirdly, the optimal threshold is determined through maximizing the entropy of fuzzy partition based on conditional probabilities and eritropy of fuzzy partition. Finally, an edge detection procedure is executed on the edge images. The experimental results show that with the proposed method plenty of lower level gray can be preserved to obtain more favorable edge detection. |
