However, you can do it into an invisible figure and then use the print function to output to an image file. I don't know whether the performance will be suitable for you or not.

For example I have circles that I am checking for their circularity and I just want to overlay text in the image itself over the circle with the circularity value. Is this possible with the current toolset Matlab provides? If not what is the recommended way to implement this?

Regards Shahn Dear Steve

I have tried relabelling objects in my binary image, using
region groups but the labelling is incohereant.

how can I relabel my binary objects row wise as :

1 2 3 4 5 6 7
8 9 10 11 12 13 etc ?????? in my case the objects represent atoms.
Regards Shahn

I get two different objects ,an object recognised in one image and in another image it is not an object . How is it possible? -swetha Hello Steve,
