PROBLEM TO BE SOLVED: To provide a method of removing blocking artifacts.SOLUTION: A method comprises determining a boundary strength for each 4-sample edge lying on a 8×8 sample grid, determining whether deblocking filtering is performed on the 4-sample edge if the boundary strength is not equal to zero, selecting a deblocking filter if the deblocking filtering is performed on the 4-sample edge, and filtering the 4-sample edge using the selected filter. Accordingly, the computational complexity required to determine the boundary strength according to the present invention is reduced by 50% or more compared with the HEVC standard whose standardization is being developed. In addition, the memory capacity and bandwidth required to determine the boundary strength are reduced by 50% or more without deterioration of video image quality.SELECTED DRAWING: Figure 1 |
