Hardware and Software Implementation of Median Filter in Image Processing Application
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 10
Abstract
[sub][sup]Image can be contaminated in the process of collection, processing and transmission. That’s why image denoising is important part of Image Processing. The existence of Impulse noise in an acquired image is most common problem. Median filter has ability to remove Impulse noise and preserve edges of an image. It is a computationally intensive operation, so processing time of median filter software algorithm is considerably more. Therefore, to meet the real-time filtering requirements, fast hardware based Median filter is used. In this work, median filter is implemented on FPGA and filter quality in terms of Signal-to-noise ratio is measured for several 256 x 256 color (RGB) images.[/sup][/sub]
