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 Regards Jens "Alexander" <beginning.physst at mail.ru> schrieb im Newsbeitrag news:dt488e$2hk$1 at smc.vnet.net... | Dear Mathgroup! | | Suppose we have a picture with a set of white circles on a black | background. | How can we count circles and measure their radius using mathematica | system??? | | Thanks for your answers! | Alexander. |
