how to store a data in array?
显示 更早的评论
my data is a centroid of 2 pictures.
clear all;
background=imread('junc3.png');
backgray=rgb2gray(background);
frame1=imread('junc3-01.png');
backgray2=rgb2gray(frame1);
Z=imsubtract(backgray2,backgray);
figure;
imshow(Z);
se=strel('ball',5,5);
dilatedZ=imdilate(Z,se);
imshow(dilatedZ)
% centroid
Zbw = im2bw(dilatedZ,0.1);
imshow(Zbw)
cent = regionprops(Zbw,'centroid');
se=strel('line',11,90);
imshow(Zbw); hold on;
for x = 1:2
plot(cent(x).Centroid(1),cent(x).Centroid(2),'ro');
end
% frame2
clear all;
background=imread('junc3.png');
backgray=rgb2gray(background);
frame1=imread('junc3-02.png');
backgray3=rgb2gray(frame1);

for x = 1:2
plot(cent(x).Centroid(1),cent(x).Centroid(2),'ro');
end

And what is your question exactly? Please provide details.

I guess you want to store centroids into an array. You can store centroids into array using:
centroids=cat(1, cent.Centroid) ;

Just before
% frame2
insert
cent1 = [cent.Centroid];
and after the end of the code you show,
cent2 = [cent.Centroid];
then cent1 and cent2 will each be numeric arrays with two rows each of which indicates one centroid.
