Something like
stats1=regionprops(BW,'MajorAxisLength','MinorAxisLength','Centroid','Orientation','Area','EquivDiameter')
centers = stats1.Centroid;

Hi,
did you mean 'find centroid of objects in an image'??
use regionprops with property : centroid
Eg : stat = regionprops(Ilabel,'centroid');
I = imread('coins.png');
Ibw = im2bw(I);
Ibw = imfill(Ibw,'holes');
Ilabel = bwlabel(Ibw);
stat = regionprops(Ilabel,'centroid');
imshow(I); hold on;
for x = 1: numel(stat)
plot(stat(x).Centroid(1),stat(x).Centroid(2),'ro');
end

Hi,
If I use this code, I get a centroid array that has 255 elements. What is the meaning for each element? Thanks!

Broad question, if the image is your input, simply find the center of the image. But I assume you are asking a more complicated question: like find the centroid of a specific object in an image? if so, need to segment the object out of the image, then find the center point.
