Vignetting, discussion about methods of resolution Options

[jaredGalen]

Hi, I haven't a much of a chance to do any coding yet.
I just want to clarify something.
MichaelT, the CONGRID command you use. I have to implement that myself but
I want to check that all I have to do is take a two-dimensional array and
subsample it down to the smaller size.

Hopefully over the weekend I'll get a chance to get something done. After the Ireland v Australia rugby match of course.

Yep, that's it

Talking about Australia:
The Socceroos just made it to the World Cup in Germany next year by beating Uruguay 4-2 on penalty shoot-out.
And I used to watch rugby, too, when I lived in Hobart in 1999/2000. Unfortunately, its impossible to watch it here.

Micheal,

I just like to say thank you for sharing your software !
As you know, I was already in the process of developing my own anti-vignetting software, implementing a similar algorithm in C,
but with the latest version of your program (with the batch mode !)
there is no need for an own AV-tool any more :-)
The only advantage of a C-based program (that I originally planned to write)
would be speed and the potential to run without additional virtual machine ... but I have downloaded and installed the IDL and it's fast enough and without hazzle and really no problem at all ... Plus: your program has the fine graphical user interface whereas most of my C-based tools are rather cryptic and mostly command line driven .. although I really would miss batch capabilities ...
So I think your latest batch-enabled version of AntiVig will definitely become the "gold standard" of Anti-Vignette processing in the MER imaging community

Thanks again !

I made a minor modification to the program. I don't know whether that will make any difference to the problem that you encountered James. Just try it out and tell me what the result is. Version 2.0.1 can be found here: AntiVig

Michael

Will do, thanks Michael,

will be over the weekend however, v-busy today/tomorrow.

You're welcome and thanks for the nice words

MichaelT,

I just downloaded Anti_Vig 2.0.1, but when I try to use it I get the following message:

"Attempt to call undefined procedure/function: Anti_Vig 2.0.1 ".

Version 2.0 works fine.

Hi Jvandriel,

I guess you renamed it as "Anti_Vig 2.0.1", right?
But it's necessary to keep the name of the program only "anti_vig.sav"

I tried that already too.

That is strange.
I just downloaded it and run it with VM - no problems...

When does that error occur? Already on start-up?

Just to be on the safe side, I re-compiled the program and put it online again. It's version 2.0.2.

You are right Tman!!!
I should have noticed that from the error message.

It is absolutely necessary to leave the name of the file as it is. Because that is what is stated in the first line of the program: its name. And that can't be changed by you.

Michael

[MichaelT]

Would you like me to include the version number in the name of the file? Wouldn't be a problem. So you could keep all the old versions in one folder and use them independently.

Michael

[Tman]

Hi Michael, just reply overlap.

Regarding version number in the name, I would like it. So one can leave the previous version just in the same file folder - I know it is not necessary but I always keep the previous for safeness.

It works!

Thanks Michael,

[MichaelT]

It works!     

Thanks Michael,

Well, I had forgotten to eliminate one little command: WAIT, 0.00001
That command makes the program wait for 1/10000 of a second.
I had to slow down the program on my comupter on purpose, when running in IDL. Otherwise it always crashed, probably due to some ram access conflicts. That wait-command is within a loop, resulting, theoretically, and on a Windows system obviously practically, in an overall delay of about 1/200 of a second. Why that causes the program to be that slow on a Mac is quite surprising. Sorry for that. In the end, all I had to do was to delete these lines. You can still find them in the code that I posted further above.

Have a nice weekend!

Michael

MichaelT and Tman,

thanks for the advice. I did indeed change the name.
Now I have downloaded Version 2.0.2 and it works perfect. ( without changing the name of course. )


MichaelT,

is it possible for you to make the following modification to your program.
Now, in batch processing mode, every image is calculated and saved.
It is not possible to individual change the brightness of an image. That must bo done later by hand.

For example,
in batchmode after calculating the image the batchmode halt, then change the brightness by hand, ok it and the batchmode continue and saves the image, calculate the next image and halt for brightness change and so on and so on until all the images are done.

Sorry, to give you more work.

I thought about these things already, too. They require some major modifications to the program.
Unfortunately, I have very, very limited time at the moment which does not allow me to tackle that task. Also, I will be away from mid December until mid January. I will not be able to answer requests during that period.
I wish I had more time for these things now as they are a lot of fun. But I have to put you off until next year.
But I promise to do it.

Michael
