Hello Everyone, With regionprops() we can find centroid of any blob, but if this is the question with thin edged (One Pixel thickness) mask then how to proceed further? I want to find the separate Centroid of both of the blob. Each of them share only one-pixel thick boundary which is common. Please find the image attached with this question. Thanking you in anticipation.

regionprops(bwconncomp((imfill(A,'holes')-A),4),'centroid')
1) Fill the holes/"blobs" in the image.
2) Subtract the boundaries from the filled image to obtain 2 disconnected blobs (4 way connectivity due to pixelization).
3) Find individual blobs.
4) Find their centroid.
