AN IMPROVED TECHNIQUE FOR ENRICHING THE QUALITY OF IMAGE USING ENHANCED NL MEANS APPROACH

Abstract

Over the years a variety of methods have been introduced to remove noise from digital images, such as Gaussian filtering, anisotropic filtering, and Total Variation minimization. However, many of these algorithms remove the fine details and structure of the image in addition to the noise because of assumptions made about the frequency content of the image. The non-local means algorithm does not make these assumptions, but instead assumes that the image contains an extensive amount of redundancy. These redundancies can then be exploited to remove the noise in the image. In this paper, we are trying to reduce the redundancies so that the quality of the image can be improved and enhanced.
