Fig. 7
Comparison between the compression performance of H.264/AVC and Motion JPEG
2000 for 720p50 and 1080i25 material (CrowdRun, ParkJoy and DuckTakeOff sequences).
These results show that for progressive material, the compression performance of
H.264/AVC Intra is better than that of Motion JPEG 2000 for CrowdRun, ParkJoy
and OldTownCross. The performance of both coding systems is comparable for
OldTownCross, while Motion JPEG 2000 outperforms H.264/AVC Intra for the
