Abstract

Very low bit-rate video coding using patterns to represent moving regions in macroblocks exhibits good potential for improved coding efficiency. Recently an Arbitrary Shaped Pattern Selection (ASPS) algorithm was presented, that used a dynamically extracted set of same sized patterns, which were based on actual video content. This algorithm however, like other pattern matching algorithms failed to capture a large number of active-region macroblocks (RMB) that cover partial moving objects in a video sequence. As the size of the moving object may vary, superior coding performance is achievable by using dynamically extracted patterns of a different size instead of a fixed size. This paper, proposes an Extended Arbitrary Shaped Pattern Selection (EASPS) algorithm that uses two different user-selected pattern sizes for very low bit rate coding. Experimental results show that EASPS exhibits significant improved performance compared with other pattern matching algorithms, including the low-bit rate video coding standard H.263.
