I have a binary image. I have several single pixels in images. Single pixels are white (1) and all of their neighborhoods are black (0). for example image below shows a single pixel (at center) and two pixels (at left-bottom):
0 0 0 0 0
0 0 0 0 0
0 0 1 0 0
0 0 0 0 0
1 1 0 0 0
How can I remove single pixels with morphological operations in Matlab?
Upon request by the OP, I'm converting my short comment into a reply:
Since you explicitly asked for morphological operations: bwmorph has a 'clean' option which is described as "Removes isolated pixels (individual 1s that are surrounded by 0s)" with an example close to yours. Have a look at the bwmorph documentation page.
