| 摘 要： | 分析了Pal模糊边缘检测算法,并针对Pal算法提取边缘轮廓不清晰的问题,提出了一种新的模糊边缘检测算法.该算法重新定义了隶属度函数,简化了复杂的变换运算,而且提出了确定模糊增强变换中最佳隶属度阈值的算法.实验结果表明,该算法提高了运算效率,而且提取的边缘比较精细.

| Abstract: | By analyzing Pal algorithm systematically,a new improved fuzzy edge-detection algorithm based on fuzzy sets is presented.In the algorithm the complex transformation calculation is simplified and the membership function is defined.In this algorithm a algorithm determining the optimal threshold value of membership function is also proposed.The experiment indicates that the algorithm is an efficient and valuable edge detection algorithm. |
