%salt&pepper椒盐噪声:黑点如胡椒,白点如盐粒,由图像传感器、传输信道、解码处理、图像切割等产生的黑白相间的亮暗点噪声。 %由于matlab的imnoise函数会将输出归一化,在读入图片时先用im2double将图片归一化,以免数据类型不同。 A=imread('BoatsColor.bmp') I=im2double(A) h1=imnoise(I,'gaussian',0,0.05)%高斯...

theimfilter()function is the image you want to smooth, and the second argument is the filter you made using thefspecial()function. For example, let’s add salt and pepper noise to a given image using theimnoise()function and then smooth it using theimfilter()function. See the code below...

The median filter is a common nonlinear filtering method, especially effective to salt pepper noise. Through wiener filtering, the gaussian noise is inhibited obviously. Wavelet coefficients threshold processing in wavelet domain can remove noise and the the signal which is not expect. Key words:...
