how to separate objects in binary image?
3 views (last 30 days)
I have binary images representing ROIs as the one attached. In this example is is clearly seen that there are 3 ROIs, 3 closed polygons. I want to separate those ROIs in order to assign a label to each one.
I've tried using bwlabel but the problem is that ROI1 and ROI3 have some connected pixels, so I can separate ROI2 but not ROI1 and ROI3.
Any recommendations of how to do this?
