Re: Counting circles (digital image processing)


Hi,

label the connected components in the binarized image.
For the radius I would suggest to use a distance transform on
the binary image and the maximum value of the distance transform
in every single unconnected component is your radius

| Dear Mathgroup!

| Suppose we have a picture with a set of white 
circles on a black

| How can we count circles and measure their 
radius using mathematica
| system???

| Thanks for your answers!
