Abstract

This paper proposes a Lifting based wavelet transform implementation of Haar mother wavelet from image compression. Discrete Wavelet Transform (DWT) algorithm using the Haar wavelet is implemented and some modifications are proposed without the increasing in hardware requirements. The Peak Signal to Noise Ratio of the reconstructed image is found to be 6.409 dB better when compared to Conventional Haar Transform.
