Title:
How to remove blocking artifacts
Document Type and Number:
Japanese Patent JP6285486
Kind Code:
B2
Abstract:
Provided is a method to determine a boundary strength for each 4-sample edge lying on 8x8 sample grid, determines whether deblocking filtering is performed on the 4-sample edge or not if the boundary strength is not equal to zero, selects a deblocking filter if the deblocking filtering is performed on the 4-sample edge, and filters 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 when compared with the HEVC under development. Also, the memory capacity and bandwidth required to determine the boundary strength are reduced by 50% or more without deterioration of image quality.
