Freeware Image Analyzer

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, 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.

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, 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)

Here's the result.

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

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

Hi Craig.

I haven’t a clue. But they obviously think it’s an improvement.

I just copied and pasted the email they sent me
