| 摘 要： | FCM(fuzzy c-means clustering)算法在图像分割中应用较为广泛,但由于其对噪声较敏感,所以只适合于分割噪声含量较低的图像.利用空间信息加权的FCM算法能够有效地抑制噪声却使图像的边缘变得模糊,造成边缘处分割的不准确.本文通过区分图像边缘点和内部点,在构造邻域平均灰度图像时区别对待,并对边缘点根据它与邻域的灰度关系进行补偿.实验结果表明,这种方法不仅能够有效地抑制噪声,并使边缘点的分割更准确,使分割质量明显提高.

| Abstract: | Fuzzy c-means clustering algorithm was widely used in image segmentation,but it was so sensitive to noise that it was just adaptive to segment images with low noise.The weight-adding FCM algorithm with spatial information could suppress noise effectively,but resulting blurry image edges,leading to more false points at the edge.In this thesis,the edge points and the inside points of an image were treated differently when calculating average neighboring value.Values for edge points were compensated according ... |
