模糊迭代边缘检测器

FUZZY ITERATION EDGE DETECTOR

该文主要研究了受不同噪声污染图像的边缘提取问题,提出了一种基于模糊理论的边缘检测算法。该算法将滤波窗内的像素看成模糊集,根据其不同的隶属度将窗内像素分成两个子集,在两个子集内进行模糊均值迭代运算,然后将收敛后的两个值通过差分运算来提取边缘。计算机模拟表明,此种方法对于高斯噪声、脉冲噪声及混合噪声都有较好的抑制能力。

This paper mainly studies the edge detection of noisy images. An edge detector based on the fuzzy theory is presented. The algorithm first makes the pixels in the window as a fuzzy set, and divides two sub-sets by their membership functions, and then iterates in the two sub-sets, lastly detects the edge by the difference of the two values from the two sub-sets. The computer simulation shows that the edge detector is good for attenuation not only of Gaussian noise but also of impulse noise and mixture noise.
