Filtering is most important and critical task to exquisite information from the noisy image and can be used in different and diverse engineering problems such as signal processing, image processing(like edge detection, object identification, brightness, contrast etc) , electronic, physics electronic, etc. Filters are used for de-blurring and smoothing in image processing and analysis,. In addition with the help of the filters some details which are clear and fair in the original image will be blurred and the ultimate final image will be enhanced. In this paper we present different types filtering techniques and have simulated some of them in Matlab.
