我需要在Matlab中创建一个GUI。它要求我确定两幅图像的斑点,并计算它们之间的距离。矩阵的Matlab GUI GUI
我已经获得了查找和包围单个点的代码。其计算方法如下:
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
不过,我需要它为多点工作,如下图所示:

到目前为止,我想出了这一点,但它只是圈出不同的景点而不是全部。 请帮助 - 我需要包围至少10X10个点并存储它们的值,并为上面显示的两个图像执行此操作,并找到它们之间的距离!
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
