Abstract
A method for determining the boundary strengths of edges in a block-based digitally encoded image is disclosed. The method includes setting the boundary strength of two adjacent blocks in an Inter macroblock to a first strength value if any one of the two adjacent blocks contains non-zero prediction residual in the encoding data and setting the boundary strength thereof to a second strength value if the two adjacent blocks are located in the same motion compensation block. An edge with boundary strength equal to the second strength value will be skipped in a deblocking process.
