Haar Wavelet Transform image compression using Run Length Encoding

Abstract

In modern technology memory storing space is not a very big deal. But when it comes to a portable system i.e. a digital camera with internet as well as communication facility, then the bandwidth for communication as well as storage are of serious concern. Huge useful information has to be stored and retrieved efficiently for practical purposes. The Haar wavelet, which is the simplest of all the 2D DWT, along with thresholding has been applied on a JPEG image. After that Run Length Entropy Coding has been adopted. This is the novel approach that authors have proposed for compression of image using parameter CR (Compression Ratio) without losing the parameter PSNR, the quality of image, using less bandwidth.
