Abstract
A video compression system is created that combines the JPEG2000 and H.264 standards. JPEG2000 is used to encode the I-frames, while H.264 is used to encode the P-frames. The goal of this thesis is to evaluate the performance of this hybrid system. The system is evaluated using a set of eight test video sequences, which cover a range of resolutions (CIF to 1920 x 1080) and picture content. Rate-distortion performance analysis shows the two systems to be comparable. Subjective analysis reveals that the artifacts of JPEG2000 are propagated to the P-frames. This can be useful in reducing blocking artifacts at low bit-rates. However, blurriness and fuzzy edges, which are the artifacts of JPEG2000, replace the blocking artifacts.
