This paper presents a novel video codec scheme which is suitable for mobile devices and is matched to their limitations. It also takes into consideration the limited computational resources in mobile devices. The coding and decoding take advantage of the wavelet decomposition, the set partitioning in hierarchical trees (SPIHT) and difference frames to substitute the complex motion estimation and compensation techniques used in modern video compression standards. A new fuzzy change detector is used to detect the changes in a video sequence and divide the sequence into scenes to be encoded independently. A further enhancement is done using a new fuzzy sequence tester to test each scene for high activity (due to motion) and decide whether or not another reference frame (keyframe) is needed. Simulation results prove the enhanced performance of the suggested codec.
