Hello, I have a binary image with one object. How can I calculate the center of this object, to mark it in my image and to write the coordinates in the corner of this image, like this: object: X, Y
I used this code to calculate the center of mass:
s = regionprops(bw, 'centroid');
centroids = cat(1, s.Centroid);
plot(centroids(:,1), centroids(:,2), 'b*')
but how can i plot this coordinates on my image in the left corner?
Thank you for help

use text command:
your_string = strcat( num2str(centroids(:,1)),'-', num2str(centroids(:,2))); text(10,10,your_string)
change the position by changing the "10,10" values
ndgrid() of 1:width and 1:height, do a logical indexing of those according to the binary image, calculate the mean() of what is left in each of the two coordinate matrices. Result will be centre of mass along each of the two coordinates.
