How can I select all the 1-pixel objects i a B/W image? Basically I’m trying to delete these scanning artifacts for text document.

Thanks for any suggestions,

trying to delete these scanning artifacts for text document.

On your Photoshop install CD, there should be a folder named "Goodies" or similar. Within there, there will be a plug-in called "Filter Factory". With that, you can set the value of all "lonely" pixels to white/whatever you need (by checking the values of all adjacent pixels).

Caveats:

1) You might need to set the image to RGB mode to run a filter.
2) I don’t know how it will behave at the edges.

Hopefully that gives you a pointer to your desired result.

Thank you for the suggestion. I’m not sure if this would work. If I can select the lonely pixels, I would just delete them wihtout using a filter to change them to white. I’m trying to select these lonely pixels.

Did I miss anything?

Thanks,
