"The general expression of a convolution is where is the filtered image, is the original image, is the filter kernel. Every element of the filter kernel is considered by and . Depending on the element values, a kernel can cause a wide range of effects. . The above are just a few examples of effects achievable by convolving kernels and images. " - Filter image processing

Filter image processing

WebIn Image processing, each element in the matrix represents a pixel attribute such as brightness or a color intensity, and the overall effect is called Gaussian blur. The Gaussian filter is non-causal which means the filter window is symmetric about the origin in the time-domain. This makes the Gaussian filter physically unrealizable.
