Abstract :
Most of the current video coding standards, such as H.261 and MPEG-1, are frame based while MPEG-1 can encode objects. Shape coding is a process of coding a visual object. This paper proposes conformance test methods for BAB (binary alpha block) decoder, CAE (context based arithmetic encoding) decoder for intra and inter VOPs (video object planes), upsampling and downsampling. Our test generates all possible cases of binary shape encoding
