Hybrid Adaptive Subband Image Coding Technique with DWT, FF DCT, and RLC

Abstract

This paper presents a new scheme for compression technique of images based on a Discrete Wavelet Transform (DWT) and Full Frame Discrete Cosine Transform (FF DCT) to code the lowest subband image, and Run Length Code (RLC) to code the other subbands.The objective of this paper is to reduce the data volume and to achieve a low bit rate in the digital representation of images without perceived loss of image quality. However, the most application of compression for transmission bandwith and storage space in the digital processing.
