Hey Guys,
I find the centroid values in an image using the regionprops command. I am able to plot the centroids on the image as well. Could anyone tell me how I can include the centroid values beside the plot. i.e. if the centroid of my image is at (3,3), i want to plot the centroid and display the value along with it. I am able to do the former and I need help with the latter.

can you explain better what do you want? 'centroid values besides the plot'

Say in a figure, a point G denotes the centroid. I know the value of the centroid to be (3,3). I want this value to be displayed near the point G on my figure.

In the link that I posted you have
x = s(k).Centroid(1);
y = s(k).Centroid(2);
text(x, y, sprintf('%d', s(k).ClassNumber), 'Color', 'r', ...
'FontWeight', 'bold');
