我需要在Matlab中創建一個GUI。它要求我確定兩幅圖像的斑點,並計算它們之間的距離。矩陣的Matlab GUI GUI

我已經獲得了查找和包圍單個點的代碼。其計算方法如下:

function [meanx,meany] = centroid(pic) 
[x,y,z] = size(pic); 
if(z==1) 
    ; 
else 
    pic = rgb2gray(pic); 
end 

% N=2; 
% image = interp2(double(pic),N,'spline'); 
image = sort(sort(pic,1),2); 
image =reshape(image,1,numel(image)); 
i=0; 
while(i<3) 
     if(image(end)==image(end-1)) 
       image(end)=[]; 
     else 
      image(end)=[]; 
      i=i+1; 
     end 
end 
    threshold = image(end); 
     pic2 =(pic>=threshold); 
pic=(pic-threshold).*uint8(pic2); 
% % image=(pic-threshold+1).*uint8(image);  %minus threshold 


[rows,cols] = size(pic); 
x = ones(rows,1)*[1:cols]; 
y = [1:rows]'*ones(1,cols); 

area = sum(sum(pic)); 
if area ~= 0 
    meanx = sum(sum(double(pic).*x))/area; 
    meany = sum(sum(double(pic).*y))/area; 
else 
    meanx = cols/2; 
    meany = rows/2; 
end 

不過,我需要它爲多點工作,如下圖所示:

到目前爲止,我想出了這一點,但它只是圈出不同的景點而不是全部。 請幫助 - 我需要包圍至少10X10個點並存儲它們的值,併爲上面顯示的兩個圖像執行此操作,並找到它們之間的距離!

img1 = imread('r0.bmp'); 
centroidmat=zeros(10,10,2); 
for numx=1:2 
    for numy=1:2 
     single_spot=img1((numx*220+780):((numx+1)*220+780),(numy*220+1272):((numy+1)*220+1272),:); 
     figure 
     imshow(single_spot); 
     figure 

     [cx,cy] = centroid(single_spot); 
     centroidmat(numx,numy,1)=cx; 
     centroidmat(numx,numy,2)=cy; 
     imshow(single_spot); 
     hold on; 
     plot(cx,cy,'og') 

    end 
end 

Please HELP GUYS!Please HELP GUYS!任何幫助表示讚賞!

這項工作? -

centroidmat=zeros(10,10,2); 
for numx=1:2 
    for numy=1:2 
     single_spot=img1((numx*220+780):((numx+1)*220+780),(numy*220+1272):((numy+1)*220+1272),:); 

     [cx,cy] = centroid(single_spot); 
     centroidmat(numx,numy,1)=cx; 
     centroidmat(numx,numy,2)=cy; 

     figure, 
     imshow(single_spot); 
     hold on; 
     plot(cx,cy,'og') 
    end 
end 

我只被移去的冗餘imshow(single_spot);在循環的開始,因爲它們稍後再次出現在同一個循環中。
