Wireless sensor networks (WSNs) are emerging in various fields like wildlife monitoring, mining industries and security surveillance. The efficiency of sensor networks strongly depends on the routing protocol used. Routing protocols providing an optimal data transmission route from sensor nodes to sink to save energy of nodes in the network. Different(More)
Image denoising problem can be addressed as an inverse problem. One of the most recent approaches to solve an inverse problem is a sparse decomposition over overcomplete dictionaries. In sparse representation, images are represented as a linear combination of dictionary atoms. In this paper, we propose an algorithm for image denoising based on Orthogonal(More)
