An Improved Image Compression Algorithm Based on Daubechies- Wavelets with Arithmetic Coding

Abstract

In this paper, we present image compression techniques to utilizing the visual redundancy and investigated. To effectively define and utilize image compression context for natural image is difficult problem. Inspired by recent research in the advancements of image compression techniques, we propose Daubechies-Wavelet with arithmetic coding towards the improvement over visual quality rather than spatial wise fidelity. Image compression using Daubechies-Wavelet with arithmetic coding is quite simple and good technique of compression to produce better compression results. In this image compression technique we first apply Daubechies-Wavelet transform then 2D Walsh-Wavelet transform on each kxk where (k=2ⁿ) block of the low frequency sub band. Split all values from each transformed block kxk followed by applying arithmetic coding for image compress.
