2) client of local area network (LAN) is handled service to the server requests parallel video respectively;
3) server sends to each client with algorithm processing module; The image sets that to cut apart is simultaneously distributed to each client successively; The image processing algorithm of client call algorithm processing module is handled each two field picture in the image sets successively, and the image sets after will handling then sends to server;
4) server generates final output video with the image sets combination.
Further improvement as technique scheme:
Server comprises input video in the said step 1) according to the detailed step that frame is divided into image sets: said server at first obtains the client terminal quantity in the local area network (LAN); Obtain the totalframes of input video then; Then the totalframes of input video is cut apart according to client terminal quantity, obtained the quantity image sets identical with client terminal quantity.
The image processing algorithm of client call algorithm processing module comprises the detailed step that each two field picture in the image sets is handled successively in the said step 3): client at first detects video card and whether supports general-purpose computations, and the image processing algorithm of the general-purpose computations interface interchange algorithm processing module if video card is supported the general-purpose computations ability through video card is handled each two field picture in the image sets successively; The image processing algorithm that calls algorithm processing module through central processing unit if video card is not supported the general-purpose computations ability is handled each two field picture in the image sets successively.
The image processing algorithm that calls algorithm processing module through central processing unit comprises the detailed step that each two field picture in the image sets is handled successively: said client is at first obtained the core and the core of processor and is supported that number of threads obtains hardware computing number of threads; Hardware computing number of threads is that unit is divided into the subimage group with the picture frame with image sets then; Then the subimage group is distributed to each hardware computing thread respectively, and the subimage group after after all subimage groups dispose, will handling makes up the image sets after obtaining handling.
The present invention has following advantage: the present invention is used to carry out the algorithm processing module of concrete image processing algorithm through the server sets of local area network (LAN); And with input video according to frame be divided into image sets, server sends to each client with algorithm processing module; The image sets that to cut apart is simultaneously distributed to each client successively; The image processing algorithm of client call algorithm processing module is handled each two field picture in the image sets successively; Image sets after will handling then sends to server, and server generates final output video with the image sets combination.Therefore can be abundant the computer resource of local area network (LAN) realize processing to video, can realize that the parallel video of local area network (LAN) is handled, Video processing is efficiently quick, easy to use, autgmentability number, be particularly useful for large-scale Video processing.
