The new Video Applications layers such as meeting frequently, videophone, monitoring remote video, Telemedicine System and digital stream media go out not
Thoroughly.These application are required for substantial amounts of image is carried out network transmission.And owing to the quantity of information of image is huge, depositing to memorizer
Storage capacity, the bandwidth of communication trunk channel, and the processing speed great pressure of increase of computer, merely by increasing memorizer
Capacity, it is all unpractical for improve the method such as processing speed of channel width and computer solving this problem, it is necessary to right
Image is compressed, and removes the redundancy in image information, reduces the quantity of information of network transmission.
JPEG is International Organization for Standardization (ISO) and CCITT combines the compression and coding standard of still image of formulation, and it is
In still image, compression ratio is the highest, just because of the high compression ratio of JPEG at present so that it is in the great multimedia of data volume
And the network program of bandwidth resources preciousness has a very wide range of applications.
When the speed of JPEG encoding and decoding brings up to a certain degree, it becomes possible to encode dynamic image, this JPEG presses
Reduce the staff code and be referred to as M-JPEG (Motion-JPEG).It is less that mono-feature the biggest of M-JPEG is exactly the image procossing waiting time, suitable
Image procossing is carried out together under such as Motion detection or object tracking environment.M-JPEG can provide all actually used
Image resolution ratio, from the QVGA resolution for mobile phone, to the full video display size of 4CIF, the most higher million
Pixel resolution.No matter system is moving or can ensure video quality in the case of complex environment, and providing high image quality (low
Compression) and the flexible selection of low image quality (high compression), can really ensure the real-time of image procossing simultaneously.
Summary of the invention
In consideration of it, the invention provides a kind of intelligent jpeg image coding/decoding system and method, the present invention has in real time
Property high, picture quality high, running efficiency of system advantages of higher.
