“Noise Color” specifies the “text” color, black and white (for example if you have a document where the text is black “Noise Color” must be black, otherwise it must be white).

“Pixels Count” specifies the isolated pixel block size to remove (e.g. 1 for single pixels, 2 for a pair of isolated pixels, etc.)

Notes:
– Big “Pixel Count” values may slow down process and cause out of memory exceptions

 

Example:

remove isolated pixels original

remove isolated pixels – original

remove isolated pixels result

remove isolated pixels – result
