In a binary image, can I selectively remove one of the blobs interactively?

As the title states, I have a binary image with a number of blobs. Can I interactively remove one or more of the blobs without too much trouble?

As in, I don't want program a code to remove, say, the 5th blob. I want to open up a figure, click on a blob, and delete it.

Label the blobs with bwlabel. Then call ginput() or impixel() and have the user click on a blob. Get the value of the labeled image at that location. Then use ismember() to erase that blob. Relabel if you want to reflect the fewer number of blobs.

You're in luck (!) - I wrote it here:
