This paper presents a small detail of implementation of 2D-discrete wavelet transform in Matlab and Xilinx system generator which offers decomposition of images using Haar Wavelet. This design is focused on less hardware utilization, efficient technique of algorithm, lower complexity than the other existing architecture schemes. The design incorporates a gray image in JPEG2000 standard which is further decomposed into (approximate, horizontal, vertical and diagonal) by applying 2D-DWT. Matlab is used to implement and verify the decomposition. The colored image is segmented into r bands, g bands and b bands. The objective of this paper is to give DWT decomposition using Haar wavelet transform which utilize lifting scheme that reduces complexity of the architecture thereby saving the power.
