Abstract:
Abstract: The discrete wavelet transform is used extensively in many applications, such as computer vision, pattern recognition, sub band coding, speech analysis etc. because of its capability of decomposing a signal at multiple resolution levels. It is also used in the field of image processing for texture discrimination, fractal analysis, and image compression. This 2-D DWT requires massive computations and hence there is a need for use of efficient architectures for the implementation of 2-D DWT. This paper focuses on comparing the performance of three types of architectures that is intended to compute the discrete wavelet transform of a 2-D signal at a faster rate. Here we present a comparative study of the computation time for a high speed 2- D discrete wavelet transform implementation using three different architectures: single-processor architecture, parallelprocessor architecture and pipeline architecture. Keywords: Discrete wavelet transform, discrete cosine transform, fractal analysis, texture discrimination.
