reconmb.m

用matlab写的仿真H.263标准的程序

function [ReconMBY,ReconBU,ReconBV] = ReconMB(WindowsY,ResidualMBlockY,...
                                               WindowsU,ResidualBlockU,...
                                               WindowsV,ResidualBlockV,...
                                               VectorH,VectorW)
%重建宏块计算
%输入 WindowsY,ResidualMBlockY 搜索窗口，当前亮度差值宏块，uint8
%输入 WindowsU,ResidualBlockU 窗口，当前差值色度块，uint8
%输入 WindowsV,ResidualBlockV 窗口，当前差值色度块，uint8
%输入 VectorH,VectorW,运动矢量
%输出 ReconMBY,ReconBU,ReconBV 重建宏块,double

mst_r = VectorH + 17;
mst_c = VectorW + 17;
ReconMBY = double(double(WindowsY(mst_r:mst_r + 15,mst_c:mst_c + 15)) + double(ResidualMBlockY));

bst_r = floor((VectorH/2)) + 9;
bst_c = floor((VectorW/2)) + 9;
ReconBU = double(double(WindowsU(bst_r:bst_r + 7,bst_c:bst_c + 7)) + double(ResidualBlockU));
ReconBV = double(double(WindowsV(bst_r:bst_r + 7,bst_c:bst_c + 7)) + double(ResidualBlockV));
