Analysis of Combined DCT-Vector Quantization Techniques for Image Compression

Abstract

The objective of image compression is to reduce irrelevance and redundancy of the image data in order to
be able to store or transmit data in an efficient form. Any image compression technique does not concentrate on reducing
storage amount of bits but also concentrate on not to lose quality of image. DCT is the more efficient method of image
compression because it has properties of good energy compaction and correlation reduction. We can merge DCT with
Vector Quantization technique. This study presents you the simulation of DCT-VQ image compression technique and
result of various parameters is compared with JPEG
