the package contains some methods of diffusion filters to smooth the noisy images without losing important data such as edges in image analysis,including anisotropic diffusion(Perona-Malik), linear isotropic,median and Low Pass Gaussian filter.

Image filter. To Read the raw data and to smooth the image via gaussian filter. The mask size is determined by user to control the smoothing level.-To Read the raw data and to smooth the image via gaussian filter. The mask size is determined by u

Smooth function is used a matrix with a 3X3 Gaussian filter kernel.

打开一幅图像，添加椒盐、高斯噪声，然后使用邻域平均法、中值滤波法、K邻近平均法进行平滑-Open an image, add salt and pepper, Gaussian noise, and then use the neighborhood average, median filter, K, close to the average method to smooth
