how to change each segments?

suppose i have given this image how to change each and every segment...

for r=1:64
        w(r)=abs(std2(double(E{r})));                  % computes the standard deviation of the values in E
%         figure
%         plot(w);
        ceil(w);
        q(r)=abs(std2(double(F{r})));                  % computes the standard deviation of the values in F
%         figure
%         plot(q);
        ceil(q);
        diff=w-q;
%         new_diff=ceil(diff)
        level(r) = graythresh(E{r}) ;            % determine Otsu Threshold value
        level1(r) = graythresh(F{r});           % determine Otsu Threshold value
        % Comparison based on Otsu's Threshold Value
        if  diff(r)>level(r)
            T=imbinarize(E{r});
            subplot(rows,columns,r);
            T=1;
            imshow(T)
        elseif diff(r)>level1(r)
            P=imbinarize(F{r});
            subplot(rows,columns,r)
            T=0;
            imshow(P)

          end
      end
here is the part of the code
