A nonlinear hybrid filter for removing fixed impulse noise (salt & pepper) noise from co lor images has been proposed in this study. Technique is based on mathematical morphology and tr immed standard median filter. Proposed f ilter is composed of a sequence of morphological standard and well known operations erosion-dila tion and trimmed standard median filter. It removes the fixed impulse noise (salt & pepper) very well without dist orting the image features, color components and edges. It does not introduce blurring and moving effects even in high noise densities (up to 90%). The standard similarity measure peak signal to noise ratio (PSNR) and computat ion time have been used to evaluate the performance of proposed hybrid filter. 2015 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47436895007 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.13 |
