RC1 deconvolution bug (osx)

[Philippe B.]

It's me again 

I tested DECONVOLUTION and I got some strange things with mask (no deconvolution rendering but patterns)
So I decided to test without mask but only a huge DERINGING to understand what happens (but use PSF generated by psf function:

image deconvolutionbug is taken with new version (it is not repeatable each time I make the process, horizontal pattern changes)

image deconvolution core 17 is taken with 1.7 version (same computer)

what happens if you turn off parallel processing in the global preferences?

[Philippe B.]

Yes ! Working as it should do with parallel processing off
Thanks for the idea ! You pointed it out

[pfile]

that confirms it then, i think there is some low level bug in how PI 1.8 is slicing up images for parallel processing. in the Debayer process the bug shows up as excessively long runtimes. i tried StarAlignment since i figured it would do a lot of multiprocessing but it worked fine. but then i remembered that juan was doing a lot of work on SA so of course it works

The same problem happens with LHE and StarMask (and probably with a few other tools, too), and the same workaround applies.

It is actually more complex than that, but the problem is in the new multithreading model implemented in version 1.8.

Philippe,

I cannot reproduce this problem with Deconvolution. Could you please upload both images (the image to deconvolve and the deringing support) so I can investigate it?

[Philippe B.]

Hi Juan
I sent you a MP with a small example

cheers

[Juan Conejero]

This bug is now fixed by update 20121229-2-module, which we have released today. Thank you for your patience, and that you for uploading the two images, Philippe.

In addition, update 20121229-4-module also fixes a similar (and closely related) bug in the RestorationFilter tool.

Don't worry Juan, a new release is not free of bugs !
It was very nice you provided us a RC1 version for testing
So I tested several process like some other peoples and we tell you where are the bug we found !

Thank you very much for your hard work and you quick reply to the coorection of the bugs ! No doubt in few weeks 1.8 will be a PERFECT release


So yesterdays... I found some strange things in SCRIPTS... lol
I will investigate more before open a topic )

cheers
