Digital Video Quality Enhancement Based On Weighted Guided Filtering Scheme
LATHA MAKKENA MADHAVI, Nuthanakanti Bhaskar · 2016
We present a weighted guided image filter (WGIF) to improve filtering and avoid halo artifacts.We know that the previously used local filtering-based edge preserving smoothening technique suffers from halo artifacts and also some drawbacks.To overcome this problem we are introducing an extension method called WGIF method.In this paper WGIF method is applied on digital videos for acquiring high quality.Actually this method is introduced by incorporating an edge-aware weighted into an existing guided image filter (GIF).It has two advantages of both global and local smoothing filter in such a way that its complexity is 0(N) and avoids halo artifacts The output of WGIF results in better visual quality and avoid halo artifacts.WGIF used in image enhancement, image haze removal.
