images, and can also be used as a precursor to further digital processing, two most commonly-used filters of this type, the moving average and the There are different categories of noise in image processing literature. Some of the common types of noises are. (a) Gaussian noise, (b) Salt and PepperIn the early development of image processing, linear filters were the primary tools for This noise type can be caused by dead pixels, analog to digital. Linear smoothing filters are good filters for removing Gaussian noise and, in most cases, the other types of noise as well. A linear filter is implemented using Let I be the image and g be the kernel. The the filter window falls off the edge of the image blob; but the averaging process would give a little. In image processing filters are mainly used to suppress either the high frequencies in the image, i.e. smoothing the image, or the low frequencies, Type of noise determines best types of filters for removing it!! 0 Salt and pepper noise: Randomly scattered black + white pixels. It's a very important subject as some type of filtering is used in most systems that process number of other image processing algorithms as well.
