De-blurring algorithm for fish eye Image on CCTV with nonlinear equation
In Jung Lee · 2008
A CCTV system reduces some number of cameras if we use fish-eye. In this case, fish-eye image distorted, we need transformation to flat images. In the center of images, a transformed image has no distortion, but at near boundary image has plentiful distortion. This distortion is caused by diffraction. In this paper, we introduce the backward solution of nonlinear wave equation for reducing blurred noise. To analysis the experimental result, we investigate to PSNR and get about more than 4 PSNR value.
