I have a black & white image of a texte document, I would like to eliminated the isolated pixel (small group of 1 to 5 pixels in the white area of the page) to keep only the black text.

Anyone have a suggestion to select those isolated pixels with Gimp ?

Thanks.

Despeckle should be able to do that, give it a try.

Thanks, I didn't knew about despeckle. Unfortunatly this plug-in in addition to remove the isolated pixels also remove some pixels of the non isolated one (letter contour). This is exactly what I'm trying to avoid. I must remember I have a monocrome image (2-bit) which greatly reduce plug-in option like despeckle.

Utitimatly what I need, is after a selection of all the black pixels, find a way to remove from it all area made of more than 5 contiguous pixels. The remaning areas of 5 or less pixels will be the small dots I want to remove.

Anyone have a suggestion how I can modify my black pixels selection in such a way ?

Thanks
