Using the RemoveIsolatedPixels function will (in my application) often remove "too many" pixels. It's only setting is how many adjoining pixels to remove. In my case, that value is 1, but I need to only remove that 1 pixel if there are no other pixels around the target pixel within a settable "buffer zone" (for example, if the isolated pixel has no other pixels within n pixels from it in any direction). Is this possible today?
If not, I'd like to put in a vote for this in a future release. |

At the moment it is not possible. However there is another method that could be useful: RemoveNoise. Have you tried it?
Using RemoveNoise you can specify number of iterations. |

I'm familiar with RemoveNoise, but I don't think it helps the situation (in fact, it might make it worse); based on my experiments, increasing the number of iterations causes it to remove even more pixels. I'm trying to do almost the opposite--only remove "truly isolated pixels", like one black pixel with no other black pixels within 3 to 5 pixels in any direction.
Is this something you could see doing at some point, maybe with an extra optional parameter to RemoveIsolatedPixels? |

| Please post a sample image and what you need to remove, just to perform some tests. |

| Can I send you a sample document privately? |
