FPGA Implementation of Image Compression using Discrete Wavelet Transforms

Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 0

Abstract

In this paper, we have proposed a DWT-based image compression algorithm via a popular Distributed Arithmetic (DA) technique for image and video compression. It is applied to determine the wavelet coefficients and so that the number of arithmetic operations can be reduced. The compression rate is enhanced by introducing RW block. It blocks some of the coefficients obtained from the high pass filter to zero. Then Differential Pulse-Code Modulation (DPCM) and Huffman-encoding are applied to acquire the binary sequence of the image. The functional simulation and performance of each module is analyzed with gate requirement, area, power, compression rate, and computation time. The proposed compression approach offers good performance in power efficiency than the prior methods. Furthermore, Altera FPGA based hardware realization shows 32% reduction in dynamic power consumption when compared to the literature.
