Hi,

i detected the blobs with the SimpleBlobDetector class . how can i draw these blobs or extract to matrix?

How do I calculate the number of pixels inside the blob? and How can I determine its coordinates on the main image? Many Thanks.

there is an example here

After when you use detect method in key point you have got blob center and surface using radius.
