A Proposed Method for Image Compression Using Discrete Wavelet Transform and Absolute Moment Block Truncation Coding

Abstract

In this paper, a hybrid image compression method has been presented. This method consists of two stages: the first involves the DWT (Discrete Wavelet Transform) which is used to convert image from spatial domain to frequency domain and the second stage involve the AMBTC (Absolute Moment Block Truncation Coding) that used to compress some of image data. The experimental results show that the proposed method has a very good performance, such it gives higher PSNR values with suitable value of compression ratio compared with the conventional method of AMBTC.
