Image Restoration using a Combinational Trivaritate Shrinkage Filter and PSO
Prabhjot Kaur, Sukhwinder Kaur · International Journal of Computer Applications · 2014
Image restoration in digital image processing is a technique through which corrupted images are modified to increase the quality of the image.A lot of research work has been done in this contrast to make the image quality efficient enough.When the noise level in the image is low , it is easy to rectify the image using general filter but the procedure is not effective enough when the noise in the image is high.To rectify highly noised images we need combinational filter which divides the images into section and perform the threshold operation according to the sections divided.In this paper, we propose a unique methodology to perform image restoration using a combinational trivaraiate shrinkage filter &PSO within the wavelet domain for 512*512 pixel size image.
