How can I fill regions?

Asked by Tomas on 2 Nov 2012

Hi, I used imfill to fill régions. In some cases imfill fill all the regions as a single region. How can I correct this?

edg = edge(I,'log',0);

Your edge filter probably had some kind of edge artifact that made a line all the way around the edge of your image. You have to find out why that is and either prevent it or break that line.

Of course. So, where did you upload your image?

Image Analyst on 5 Nov 2012

It's not clear what a region is, but I can tell that using an edge detector will not get them. You may have to do it manually with imfreehand().
