FPGA Based Implementation of Video Denoising Using Warped Filter

چکیده
Noise in video signal plays a major problem in most of the communication systems. Video denoising is the process of removing noise from the video signal. In order to increase compression effectiveness and improve subjective quality of video sequences video denoising process using Warped Filter is done. Warped Filter is an all pass filter; it is widely used for various video and audio processing applications. This project proposes the design, simulation and implementation of a real time video denoising on FPGA. Contourlet transform is proposed as an alternative over Wavelet transform. The Gaussian noise presents in the input signal is removed effectively. Initially a software model is constructed using MATLAB, and then with the same data’s, the hardware implementation using FPGA is done for the proposed Video denoising architecture.
