The video coding techniques such as MPEG-1 and MPEG-2 are widely used in video distribution over the Internet, DVD, etc. These video coding techniques achieve efficient compression by using block-based DCT and motion compensation. Nevertheless, there is a problem that blocking and ringing artifacts appear in the decoded images at low bit rates. Therefore, the proposed method utilizes a two-dimensional FIR filter to reduce these artifacts. The filter is to minimize the error between the original image and the coded image, and its coefficients are added into the bitstream. By applying the filter to the decoded image, the proposed method improves the decoded video quality. |
