COMPARATIVE ASSESMENT OF DIFFERENT TYPES OF DCT IN IMAGE COMPRESSION

In this paper, we compare the different types of Discrete Cosine Transforms(DCT) techniques employed in Image and Video Compression along with aApproximate DCT..This new DCT employed is a multiplier free DCT which involves only addition operations. This new DCT employed will give low complexity and efficient throughput for operations.weanalyse the different types of DCT and their Performance.
