I'm not sure what that means. Do you want to create a new image where each blob is replaced by a perfect circle that would have the same area as your original blob? If so, use regionprops to get the EquivDiameter and Centroid, and use the FAQ on circles to place a circle at each centroid.

 by finding centroid using regionprops we can place a circle at each point,,, but i want to make those small white dots to circular shape (ie., adjusting it's shape to circular like using some erosion and dilation processes )  Is there any way to cut large blob into two small blobs... ?
Thanks in advance.. :)

The FAQ shows you how to make circles.

You can use watershed to cut a blob into two parts.

I still don't understand your question or your reply.

Sorry for my English..

The blobs in the image are random in shape (some are round & some are triangular and some are polygons), i want to make every shape in that image as round (circular) & Cut the Large area shapes into two halfs..

Thanks for the replay
