Super Resolution for Fast Transfer of Graphics over Internet

Abstract

The Internet has become an indispensable component of today’s transacting world. Though a powerful medium, the Internet cannot always quickly transfer web page having image in its current form. Such web pages not only take long time to reach their destination but sometimes completely slow down or block other traffic on the network. To improve response time, in this paper we propose real time technique as an efficient way out for. We propose to transmit low resolution (LR) image at the transmitter, and show high resolution (HR) image at receiver. At transmitting end, special filter is applied to HR image to yield LR image and high frequency components. These high frequency components are used to build a basis function, which is optimal in size, and is sent along with LR image. HR image is reconstructed using these two at receivers end. For proposed approach the quality of image is better and time for transmission is less than that of conventional approaches. Simulation results show the validity of our approach.
