Centroid of thin-edged (One Pixel thickness) connected blobs

3 views (last 30 days)
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.

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.
