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

Examples here (http://meesoft.logicnet.dk/Analyzer/help.htm)

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.

Ken

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.

dc

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!

craig

Darn! Windows only as far as I can tell...

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.

I think its going to take us a while to work through all the features of this great little program. I’ll keep posting tips as I find them.

Here is a start.

Meesoft gives away several programs apart from Image Analyzer

Image Analyzer
Popims Animator
Diagram Designer
Commander
SmartMorph
Log Paper
FontView
HTML Optimizier

They are all available here
http://meesoft.logicnet.dk

There is also a support forum for each here

http://support.meesoft.com/


There are some plug-in’s available for Image Analyzer

Microscopic imaging
3D modeling
Batch processing
Fractal interpolation
TIFF reader
Extended JPEG import
Profile line
PCA Color Stretch
Developers' information

They are available here
http://meesoft.logicnet.dk/Analyzer/plugins/index.htm#MultiFocus


More to follow.

Ken

I have joined the Image Analyser Forum so I can post questions there. If anyone wants to make any suggestions or Bug reports for updates in future versions you could post them here and I will group them together to post on their Forum.

If there is enough interest I could invite Michael Vinther who is the software developer to post here.

If anyone is interested in learning more about this stuff there is a good ebook here.
http://gimp-savvy.com/BOOK/index.html

I have (so far) only concentrated on the FFT bit and found this

Press P to preview while in FFT
Arrow UP/Down to adjust Pen Size
Press the Left Mouse Button to draw a line and the Right mouse Button to draw a Dot.
Space / Enter = OK

There seems to be NO Undo. This will be my first suggestion for the next version (Unless someone has found one)

The view Scale is a little confusing. The FFT Expands but the Painted stars Don’t?

There is no more info at Meesoft. (I have read nearly all the posts.)

I believe that if you have a three button mouse (I don’t) there are more features available. Perhaps if you have a three button mouse you could post what you find.

Beware of typing stupid things into the calculator (Help > Expression Evaluator) The program can crash and you loose your work.

Ken

Hi Everyone

Just a note to mention that Version 1.25 is now available.

http://meesoft.logicnet.dk/


There is also some interesting discussion on the resizing methods here

I will have to look at this as it seems every candidate I get for FFT seems to only improve slightly, and never offers up clear star patterns this may help in those we shall see.

Wow Adaptive noise reduction worked great, I tried FFT did not see much change, the I did an adaptive noise reduction and the pattern was gone. Very sweet.

InPainting.

Image Analyzer has a Texture Synthesis filter. Now if we could get this working we could have a very powerful repair tool

I have listed some basic steps to try to get things started. I haven’t a clue whether this is right or whether there is an easier way.

1) Open Tiger in Image Analyzer

2) Use the Tool Selection (Arrow Down) and choose the Paint Selection

3) Click Brush Size and change to 30

4) Now zoom in and carefully paint over the bars. If you make a mistake use the right mouse button to delete. This selection method is a little strange to PS users (well Me) but once you get used to it, it works very well.

5) Click Special > Texture Synthesis. Method stochastic. Target Inside.

6) Click Synthesise.

That’s is. There is probably an easier way. And I think there may be some way to put the texture back as well,

This example is probably not the best. But I think this could have a lot of uses in restoration.

Ken

Ken, I don't know if we're being "unfair" using this image.
Or, maybe (probably), we just haven't learned how to drive these things yet.

Seems that they start out in the right direction but don't get very far. How long did this take to run?
Using the greycstoration program I set 500 iterations (but 499 of them didn't seem to make any difference) and it took about half an hour.

I should probably be shunting the two inpainting threads together, but I'll have to visit the sandbox to train my admin-fu first.

Rô

Hi Rô.

The Texture Synthesis takes about 5 seconds to run.
If you look in the ‘Method’ box there are four methods
Median
Average
Stocastic
Source Match

The first three are quick but the ‘Source Match’ Takes forever. Meesoft recommend a source no bigger than 64x64 but even this is slow.
The source match is the one that seems like it should put the texture back but I can’t get it to work like I think it should.

Looking at my picture again I think I should have increased the feather on the selection brush. Also selecting each Cage Bar separately would have helped because the Average or Median method would have been better in some areas. I chose the Stocastic method because it seemed better overall
I think I could have done a lot better.

Some of the examples at Greycsoration are very impressive. Maybe we should see if we could recreate one of those. Looking at your picture Greycsoration may be slightly more powerful. But as you say ‘maybe (probably), we just haven't learned how to drive these things yet’

Ken

Ken, I followed your instructions. Now I'm starting to get the hang of this thing.

I tried an easier image. Taking someone out from the front of some shrubs.
The real winner method here is the (you guessed it) source match.

Try this. Find an area of your image that has the sort of texture that you're going to use for the fill-in. Do a square selection and copy that to a new (small - like 64 x 64) image.
Now set up the selection that you're going to fill-in (like before);
Call up the Texture Sythesis and select Source Match;
To the left side you'll see the small image is listed as a choice, choose it.
Run the Sythesize, takes a couple of (dozen) minutes and bingo!

Seems to me that it's just doing the same as the patch tool in Photoshop, copying texture from one place to another - and taking an awfully long time to do it.

The greycstoration program, on the other hand, promises (hasn't happened with me yet) to interpolate the surroundings and form the missing parts - without giving it some initial texture to chew on.

I'm doing the tiger now, but there's still 30 minutes to go! (and it's way past bedtime)

Rô

Here's the result.

It did synthesize bits of tiger all over the shop, just didn't fit in too well with the surroundings.

Rô

Hi Rô

Your picture is very similar to what I got with source match. I hoped it would be better. I thought I was doing something wrong. It looks like cloning would be better and quicker. Greycsoration did a much better job
I think this tool may be better used as a de-crack or spot remover. It does say in the manual that it is for hole filling.


Re FFT
When using FFT there is an option ‘View Scale’ I thought this was magnifying the view but I was wrong. The ‘View Scale’ is more like a brightness scale
