Reliable and high speed communication over power lines requires a robust modulation scheme, like a Discrete Wavelet Transform (DWT) based modulation technique, hence the quality of data communication over the noisy in-home power line network can be improved. This paper investigates the performance of conventional Orthogonal Frequency Division Multiplexing(More)
Recently, sparse representation based visual tracking methods have attracted increasing attention in the computer vision community. Although achieve superior performance to traditional tracking methods, however, a basic problem has not been answered yet — that whether the sparsity constrain is really needed for visual tracking? To answer this question, in(More)
This paper presents a static gesture recognition system for recognizing some selected words of Persian sign language (PSL). The required images for the selected words are obtained using a digital camera. The color images are first resized, and then converted to grayscale images. Then, the discrete wavelet transform (DWT) is applied on the selected images(More)
