blockquant263.m

用matlab写的仿真H.263标准的程序

function BlockQCoeff = BlockQuant263(DctCoeff,Qp)
%h263方式量化
%输入 DctCoeff: Dct系数，8x8,double
%输入 Qp: QP, double
%输出 BlockQCoeff:已量化系数

msg = nargchk(2,2,nargin);

if ~(isempty(msg)) %检查输入参数是否为2个
    disp(msg)
    return ;
end
BlockQCoeff = round((DctCoeff/(2*Qp)));
