1.8 RC3 PixelMath hangs OSX
« on: 2013 January 28 07:28:37 »
Hi,

I have a bug on my Mountain Lion iMac al PixelMath.

PixInsight 1.8 RC3, updated, and MacOSX totally updated.

For instance, I have two luminance images, I add them over the first one, and if I close the second image (after the addition), the Pixinsight freezes (the colored turning wheel never stops). The other applications are OK, but PI is hung.

Regards,
Fernando Huet

I cannot reproduce this problem on any platform (Linux, Windows, Mac OS X).

Anybody else has seen something similar?

Fernando, does this happen consistently, or have you seen this happen only once (or sporadically)? Could you upload two images where this happens?

I dont see it on Linux.

Fernando, maybe you can also provide the exact formula you are using, and the output you see on the Process Console. Maybe provide a screenshot of your PixelMath window. Maybe it depends on the exact sequence of events/formula/option/...

Hi all,
Sorry for not responding until now... I have just been father of a precious girl  :D :D, and for a couple of days, I'm at the hospital. I'll try to reproduce the error when I'll be back at home.
But in fact, I was working with  the luminance extracted from an image, and using PixelMath to get the bigger structures and then increase the luminance.

I made:
From an Image:
Extract Luminance (Luminance1)
Duplicate the luminance
On the duplicated luminance: ATW wavelets 1 to 6. R eliminated. (We get only stars)
PixelMath: Luminance1 - Duplicated Luminance, without rescaling (we get only bigger structures) applied on Luminance 1
Exponential transf. on the result (PIP: 2)
Script DarkStructureEnhance (4 iterations x 0.1) on the result.
PixelMath: Luminance 1 after Script + duplicated Luminance (that one with with only wavelets 1 to 6)

After that, I close the duplicated luminance, as there is no need to keep it.... And after that, Pixinsight hangs and close unexpectedly.

Every time I try this, it hangs.
But if you don't use the DarkStructureEnhance, and do all the rest, the Application it's ok.

Could you try it?
Thanks,
Fernando

Well, I'm at home now and I have made some videos showing the possible bug.

I think the problem is not in the PixelMath tool, but in the DarkStructureEnhance script.

If I do 4 iterations of 0.10 in DarkStructureEnhance script, the PixInsight crashes:

I can reproduce that in every image I try.

But if I do only 1 iteration of 0.40, all is OK:

Thanks
Fernando
