Abstract
Conference Title: 2014 Global Summit on Computer & Information Technology (GSCIT) Conference Start Date: 2014, June 14 Conference End Date: 2014, June 16 Conference Location: Sousse, Tunisia Discrete wavelet transform (DWT) has diverse applications in signal and image processing fields. In this paper, we have implemented the lifting "Cohen-Daubechies-Feauveau 9/7" algorithm on a low cost NVIDIA's GPU (Graphics Processing Unit) with MatLab to achieve speedup in computation. The efficiency of our GPU based implementation is measured and compared with CPU based algorithms. Our investigational results with GPU show performance enhancement over a factor of 1.82 compared with CPU for an image of size 4096×4096 pixels.
