main.m

用matlab写的仿真H.263标准的程序

function main(source,destination,StructParameter)
%main tester

SrcFid = fopen(source,'r');
DestFid = fopen(destination,'w');
keyframe = 0;
framenum = StructParameter.framenum;
resolution = StructParameter.resolution;
for i = 1: framenum
 CodingType = 1;
 
[Y,U,V] = ReadFrame(SrcFid,resolution);
fclose(SrcFid);
SrcFid = fopen(source,'r');

if keyframe == 0 || keyframe == 200
    keyframe = keyframe + 1;
    CodingType = 0;
end
if CodingType == 0
    [RY,RU,RV] = IFrameCoder(Y,U,V,StructParameter);
else
    [RY,RU,RV]  = PFrameCoder(Y,U,V,RY,RU,RV,StructParameter);

end
WriteFrame(DestFid,resolution,RY,RU,RV);


end
fclose(SrcFid);
fclose(DestFid);
