i1 = cc(1:96,1:96);
i2 = cc(1:96,97:192);
i3 = cc(97:192,1:96);
i4 = cc(97:192,97:192);
y = {i1, i2, i3, i4};
o=[];
for i=1:length(y)
  ui=edge(i,'canny');
  count=length(find(ui(:)==1));
  o=find(max(count));
end

Who are you asking?

By the way, you posted your question just before midnight in my time zone. The volunteers in Europe are asleep, and the volunteers in North America are either asleep or just about to go to sleep.

在 MATLAB Online 中打开

for i=1:length(y)
  ui = edge(y{i},'canny');
  count(i) = length(find(ui(:)==1));
end
[~, o] = max(count);

Azzi specializes in control systems. He edits Questions of all sorts to make them readable as a service to others, but he would not typically answer this kind of question.
