I have BW image of a scanned text. There are remaining black spots, much smaller than the text.
Is there a way to remove a cluster of black pixels, surrounded by white pixels? I looked at morphology, but I have trouble achieving the effect. With cluster, I mean a connected area of black pixels.
Something to the effect of:
Code: Select all
-fill white -cluster 10x10 -opaque black
Where cluster contains at least one black pixel, has a maximum dimension of 10x10 (thus may hold up to 10x10 black pixels), and the outer edge of the cluster is white.
