Freeware Image Analyzer

This is freeware, but requires more brainpower than I have.

Examples here
Download here

Among the things its said to do:

Restoration by deconvolution
This feature will allow advanced reconstruction of blurred images.

Adaptive noise removal can remove high-frequency noise from most images.

Texture synthesis is a tool for generating textures from a sample or filling holes in an image.

Doug,

Thanks for this post. I downloaded the software and used the deconvolution here.

It seemed to help.

Thanks for the link Doug.

This is such a good little program that I thought this thread deserved a bump.

Thanks for the bump.

That's quite a piece of work. I sorta feel as though I should be wearing a lab coat to use it.

doug,

that's a great find. have already used it on one image. the sharpen/smooth tool alone is worth the price of admission. and so far, the texture adding thing wont accept even the smallest values, so have to do some study on that one. most of it shld be fairly easy if you know ps or psp or the gimp. and some, well, more play is needed yet.

also, check around on their pages. there are plugins for this thing!

Sheesh! Looks like I'm going to have to write ANOTHER FFT tutorial.
The FFT filter is very interesting - almost in real time, and only half the stars.

The program doesn't have the bells and whistles of PS and PSP tp make it more user friendly - no masks, no layers etc....

But at this price who's to complain!

Has anybody else tried using Discrete Cosine Transform on paper texture?

I’ve used the Frequency Domain Filter and it’s great. The preview means you can see the effects as you work.

I really don’t know what the Discreet Cosine Transform is used for (It looks similar). But you have to save this as a MAP file to work on it I think.

I was experimenting with the FFT filter which was working pretty well except that it left some bands of unwanted texture top & bottom. Out of curiosity I ran the discrete cosine transform (having no idea what it was) I got a cluster of dots in the upper left-hand corner and a few scattered elsewhere. What the heck - I erased the errant dots, inverse transformed and -voila! Darn near perfect. To use it with PS I think you have to convert your image to L*a*b, copy the lightness channel, paste that into Image Analyzer, run the transform on it, then select Map>Make Image (I think that's what it says) then copy & paste the result back into the lightness channel in PS.
It seems to work pretty well but it's reeeeeeaaaaaal sloooooooooooow.
