IMPLEMENTATION OF DWT USING HAAR TRANSFORM WITH FELICS ALGORITHM

Abstract: This presents an approach towards implementation of the Discrete Wavelet Transform (DWT) for image compression. The design follows a specific standard and can be used for lossless compression. Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. The demand for obtaining a higher quality images and transmitting them over the internet has created a strong need to develop algorithms and coding for such images. The algorithm included in this paper is the Felics algorithm which includes adjusted binary code & golomb rice coding. Transformation used is the Haar transform since it is advantageous over other transforms.
