This book concentrates on removal of SPN,RVIN,Gaussian & Speckle noise from images.Most of the nonlinear filters used in removal of impulsive noise work in two phases,i.e.detection followed by filtering only the corrupted pixels keeping uncorrupted ones intact. Performance of such filters is dependent on the performance of detection schemes. In this book thrust has been put to devise an accurate detection scheme and a novel weighted median filtering mechanism. Comparative analysis has been made with existing standard schemes with suitable parameters such as Peak Signal to Noise Ratio (PSNR),Access Time & Image Enhancement Factor.I am thankful to Prof.Dr.David Ebenezer,The experimental methods and results presented in this book have been in?uenced by his article.
