Abstract

Noise is impulse on images due to several factors like malfunctioning in pixels due to camera sensor, transmission of images in noisy channel, hardware problem etc. This paper surveys various techniques for removal of impulse noise. To reduce the impulse noise level in Digital images various filters were introduced amongst which (SAM) Simple Adaptive Median is one of the method, which uses hybrid technique of adaptive median filter and switching median filter. Based on Local noise level on digital images size of filter is changed i. e. square filter technique is used basically in SAM. SAM was compared with three derivatives namely Weighted SAM (WSAM), Circular SAM (CSAM) and Weighted CSAM (WCSAM) and images were restored maximum of impulse noise, but as Circular filter has complicated implementation that resulted in increase of execution time. This paper investigate the effect of shape and weight on digital images using SAM filter and restore all the digital images impulse with noise with reducing execution time for all three derivatives.
