MATLAB——图像分块

function [n] = fun(img)
M=10;N=5;%M、N选择 
[m,n,c]=size(img);

%xb xy 为xb*xy
xb=round(m/M)*M;
yb=round(n/N)*N;%找到能被整除的M,N


rgb=imresize(rgb,[xb,yb]);
[m,n,c]=size(rgb);
count =0;
for i=1:M
    for j=1:N
        % 1） 分块
        block = rgb((i-1)*m/M+1:m/M*i,(j-1)*n/N+1:j*n/N,:); % 图像分成块
        count = count+1;
    end
end
n=count;
end
