Relaxed Median Filter: A Better Noise Removal Filter for Compound Images
Journal Title: International Journal on Computer Science and Engineering - Year 2012, Vol 4, Issue 7
Abstract
Image filtering techniques are widely used in removing noises in images. But representation of data is becoming popular day by day using compound images. So, noise removal is necessary to maintain the quality of the compound images. Noise can be added to the compound images during image acquisition, image capturing or image transmission. Different literature study shows that many filtering techniques are presented to remove noise or improve the quality of the corrupted images. This paper deals with the performance study of Median, Relaxed median, Wiener, Centre weighted median and Averaging filters to remove Salt and pepper, Gaussian and Speckle noise in the compound images. This paper proposes relaxed median filter performs better for compound images.
