IMPROVED SVD - WDR BASED IMAGE COMPRESSION USING GRADIENT BASED OPTIMIZATION

Mage compression has become very important tool in digital image processing. The main objective of the compression is to reduce the amount or unwanted data while retaining the information in the image. The goal behind is to save the amount of memory required to save the image(s) or to utilize network bandwidth in efficient manner. In this paper, a new method has been proposed in order to reduce blocking and ringing artifacts in compressed images. The proposed compression technique has integrated SVD - WDR compress ion with Gradient - based optimization approach for reduction of blocking artifacts in images. The edge restoration method has also been used as a post processing technique to remove the ringing artifacts from the compressed images.
