| 摘 要： | 为滤除数字图像中的椒盐噪声,在图像灰度空间上引入模糊划分和像素点灰度值检测噪声,进而利用滤波窗口内非噪声点灰度值描述中心点的灰度水平.依据改进重心去模糊法设计一种模糊滤波器,模拟实验表明该滤波器可以有效地滤除图像中的椒盐噪声.

| Abstract: | To remove salt and pepper noise in the digital image, fuzzy partition and pixel grey values in the image space are introduced to detect noise, and then the non-noisy pixel values in the filter window are used to describe grey value level of the center pixel. A fuzzy filter is designed based on improved eentroid defuzzifieation method. Simulated examples are employed to demonstrate that the proposed filter can remove the salt and pepper noise in the image efficiently. |
