FFT registration script fails

[georg.viehoever]

Hi,

I believe this has already been reported a number of times, but I could not find a fix for this. The FFT registration script fails with:

Code: [Select]

...
*** Evaluating FFT translation:
FFT: 100%
Inverse FFT: 100%
Rescaling pixel values: 100%
*** Translation corrections:
dx :   +31.48 px
dy :   -13.66 px
*** Applying translation:
Translate dx=31.479, dy=-13.662, Bicubic Spline Interpolation, c=0.30: 100%

And yes, I probably need rotations.

Yes... known issue.

Use the module I wrote instead.

Hi Carlos,

I was just hoping that there was a patch after all this time... Also, your module does not support rotation (AFAIK).

A question to you and Juan: Why do such modules not find their way into the official release (maybe as user provided modules)? After all, Carlos is a PTeam member, several users found his modules useful, and there should have been enough time for a code review? With the new update system, it should also not be difficult to deliver such modules between releases?

Nope, no rotation. The rotation in the script also doesn't work very well. The reason is that the main routine in the FFTRegistration class is the one that needs to be improved. I implemented it, with a few extra features So, until Juan fixes that in the PCL, we'll have to wait for FFT rotation and scalations.

BTW, the calls to the rotation and scalation routines have been wrote into my code, but commented until they work. So, once this is ready, it should be a matter of a day to get everything running.

Hi,

This bug has been fixed in PixInsight Core 1.7.0.696. The new version is now available as a regular update for Windows x86 and x64.

Thanks for your patience!
