pattern in paper?

I've scanned this for a friend and it's the 1st time I've seen this. Does anyone know how I can work around this pattern in the paper? This will be a tough one!
Thanks......

Redo the Paper

Well sometimes I just redo the background. In this case I selected Peeps and copied her to a new layer. I then added a background in the layer below her.

shdyldy,

welcome to RP!

i used paint shop pro 9's jpeg artifact remover at high 75 and it seemed to handle it fairly well. that is, if i'm reading what you're trying to get rid of correctly.

after the jpg remover you can try some smoothing filters, like median or salt and pepper or edge preserving smooth. i tried the median on the lowest setting and it was semi-ok, but required some other clean up after that. so, pick your weapon and give it a go.

but just to make sure we're talking about the same pattern, do you mean that sort of checkerboard pattern of light and dark or something else?

Craig

I found a gaussian blur of as little as 0.6 was sufficient to remove the patterning. If you are concerned about the loss of detail then rather than overlaying with a highpass filter which restores the pattern, I'd use an emboss overlay just to sharpen the edges.

I had to go up to 3.4 on the higher resolution one that I have to get rid of it. I don't have Paint shop. I'm working with CS2 and not a whole lot of experience with this. I cut a part of it out so you can see it better at full size....

Not sure what you mean by full size image, I thought I had the full size image. My apologies, on your added shot, yes it takes till about 3.4-3.6 gaussian blur to remove the pattern.

I resized it to the 800x600 100KB posting rules. It's actually 2896x3936, 1000 resolution in Photoshop. Is that my problem?

You should be able to reduce the pattern somewhat using the fourier transform filter. You should be able to locate it doing a google search. Also, there is a tutorial on this forum on how to use the filter.
