| Abstract: | This paper briefly introduces the main video compression standards,then compares the advantages and disadvantages of JPEG2000 with that of other standards.The coding techniques used in JPEG2000 are also presented.The paper proposes that JPEG2000 applied in video compression,and gives a hardware and software design of embedded system.Test result shows that the quality of an image recovered from compressed video is satisfactory when compression ratio is 41.Combining decimating and inserting frames,this systemcan be used in high quality image surveillance, and soon. |
