Abstract
Very low bit-rate video coding using patterns to representmoving regions in macroblocks has very good potential forimproved coding efficiency. It is intuitively evident thatinstead of using a codebook of predefined patterns,superior coding performance is achievable if anapproximation of shape is made by using a set of patternsdynamically extracted fiom the video content. This paper,proposes an Arbitrary Shaped Pattern Selection (ASPS)algorithm for very low bit rate coding. ASPS generates aspecific pattern set of user-selectable size by applying aclassifier, with the subsequent coding b e i i performedusing these patterns. Experimental results show that ASPSexhibits better performance compared with other patternmatching algorithms, including the low-bit rate videocoding standard H.263.
