Image compression using HAAR discrete wavelet transform
Hemalatha Kanagaraj, V. Muneeswaran
Abstract
Image Compression aims at minimal the Storage and for the easy transmission Without affecting pictures quality. In this paper HAAR wavelet based Discrete Wavelet Transform (DWT) is done for the effective and efficient image compression..HAAR DWT provides an easy way of compression as the coefficient are either 1 or -1.The wavelet transforms are used for the time and frequency analysis. In this paper higher compression ratio is obtained after three levels of decompositon. The decomposed can be reconstructed without appreciable loss in the original image.
