coarseness.m%graypic为待处理的灰度图片，2^kmax为最大窗口 function Fcrs=coarseness(graypic,kmax) %获取图片大小 [h,w]=size(graypic); %平均灰度值矩阵A A=zeros(h,w,2^kmax); %计算有效可计算范围内每个点的2^k邻域内的平均灰度值 for i=2^(kmax-1)+1:h-2^(kmax-1) for j=2^(kmax-1)+1:w-2^(kmax-1) for k=1:kmax A(i,j,k)=mean2(graypic(i-2^(k-1):i+2^(k-1)-1,j-2^(k... 阅读全文
