Accepted answer

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

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.
