Method for generating distances representative of the edge orientations in a video picture, corresponding device and use of the method for deinterlacing or format conversion |
摘要 |
The distances representative of the edge orientation at a current points of a video picture generated are particularly used for the deinterlacing or format conversion of video pictures. It can be implemented in a video coder or decoder. According to the invention, the distances representative of the edge orientation calculated are filtered with a conditional median filter applied to a window of p by q distances. This filter only takes into account the distances of points for which the local gradient module of the video components is greater than a threshold. |
