Gaussian filter is a linear smoothing filtering, applicable to eliminate the gaussian noise, widely used in image processing of the noise reduction process.Popular speaking, gaussian filtering is a process to the weighted average of the whole image, each pixel values, all by itself and other neighborhood pixels after the weighted average.Gaussian filtering concrete operation is: use a template (or convolution mask), the each pixel in image scanning and templates are used to determine the weighted average grey value of pixels in neighborhood to replace template center pixel value.
