Calibration and align batch operations

[georg.viehoever]

Most likely memory shortage.
- Monitor memory usage using Windows Task Manager
- Try reducing the Buffer- and StackSize parameters
- Do yourself a favor, and upgrade to 64bits Windows. It helped a lot with my laptop, which is similar to your system.

But isn't posiible to manage these parameters with the sript ... 

Now I realize that a similar problem was reported month ago with image integration http://pixinsight.com/forum/index.php?topic=3877.msg26615#msg26615; and this http://pixinsight.com/forum/index.php?topic=3545.msg25044#msg25044, to that the first links; and others. The mine seems simply another instance of the same matter...

Hi there!

New version 0.4 attached to this post. This version is able to calibrate and align DSLR and OSC raw frames directly, without any previous conversion to the FITS format:

* Direct integration of CFA images (CR2, NEF, DNG, OSC, etc.) for master bias and dark generation. Requires the latest versions of the ImageIntegration and DSLR_RAW modules, which we have just released.

* Exposure times acquired from EXIF metadata for file formats different from FITS (e.g. DSLR_RAW and TIFF).

* New file list management functions: remove selected and invert selection (useful to handle master frames).

* Improved diagnostic information generation.

* Many minor bug fixes.

Please test it and report any bugs and problems that you find. Enjoy!

I think a 64bit OS will solve the problems. You can also try to edit the script II parameters manually (see some pages below)

Excellent news. Use of image metadata directly from DSLR files will help in several other projects.

I guess Nikolay is already working on such tool. This task should be performed to filter out bad images before calibration and alignment.

Yes, it's true. Also it will show field curvature in 3D.

Hmm, Voronoi diagrams? What are you doing with Voronoi diagrams?

Hi

I can not get my images to calibrate correctley 
I am using master bias / darks prepared in astroart will this have a effect if so why ?

console log, error messages?

Hi

Sorry , should have made it clearer 

The script works , just does not correctly calibrate my images ?

I'm use Delaunay triangulation to building a grid of FWHM/roundness/etc in the image.

Script works very nicely for me. I did not observe the change color balanced observed by someone else. My remaining wishlist:
- Integration of DefectMap/CosmeticCorrection
- Due to frequent memory shortage problems: You may want to make the integration parameters BufferSize and StackSize configurable. Even better: Let the user only specify maximum memory consumption, and let the script estimate good BufferSize, StackSize parameters from this and the number of images.
- some progress indicator (at least on the Processing Console, something like "5 of 99 images processed")
- you may want to reconsider the layout: most tools have a vertical layout, this script has a horizontal one. Since I arrange my image to fit the vertical tools, the script does not really fit in.

Fantastic work!

I have these memory shortage and have followed the advices of Georg and Kai:

1) I have loweerd the values of BufferSize and StackSize
2) directly in the code of the script.

Now my "normal" configuration woks well (Win 32 and 4 GB) , without problems of memory, and for me isn't more matter.

But, do you think that a new user or one that aproaches for first time PI soll crak the sript? I think sincerely that isn't good for PI nor for the user (that most had a "normal" configuration).

I agree. Maybe it is possible to determine a default config for those parameters based on machine characteristics (such as available RAM, OS).

The script is still not released and windows xp 32 is not officially supported by PI (so far as I know). So I have only written these vars to the script code. To avoid overloading of the GUI components I have not yet exposed these vars by adding controls. Again I think a 64bit OS will solve the problems.

Looks like no calibration at all. Is it the integration result of the /registered/ folder?
