Best regards,

Sliders improved: range automatically set to :  Min<->Mean for DeadLevel  ,   Mena<->Max for HotLevel

b0003:
CFA Bug fixed.

b0005:
memory leak Bug fixed. Engine improved.

Hi Nikolay,

thanks for the module, it installs and runs fine. There seems to be some bug though, probably concerning CFA images. Please take a look at attached images:
no_correction.jpg - calibrated image (debayered and STFed for viewing) with no correction applied. Debayered hotpixels are clearly visible.
script_correction.jpg - same image after CosmeticCorrection script applied (again debayered and STFed for viewing). Hotpixels are gone.
process_correction.jpg - same image, but corrected with your new process. Hotpixels somehow replaced with different colors, but still there.

Is the CFA checkbox value used?

Also, there's strange difference between script and process in number of reported hotpixels - for same master dark and same threshold, both report quite different number of hotpixels.

hope it helps,

Zbynek

There seems to be some bug though

Can you upload your files? Crop 100x100pixels enough.
Because I can't reproduce the problem at my files.

There are bug in script version. Actually in script calculated only pixels in Red color channel, so really processed much more pixels.
I will update script version soon. Also I think calibrate color images not good idea. Anyway I must add independent slider (  hotLevel, deadLevel, HotQty, DeadQty ) for every color channel.

Hi Nikolay,

here are the 100x100 files.

here are the 100x100 files.

Hi Zbynek,
Thank you for files. The bug fixed.

Best regards,
Nikolay.

[zvrastil]

The bug fixed.

Confirmed! Thanks a lot.

Hi Nikolay,

would it be possible to add file "Prefix" parameter as well? I like using prefixes when I calibrate or register images, as prefixed files form continuous block in default directory listing and are easier to pick all of them in Open File dialog.

best regards, Zbynek

One other thing. Seems there's a memory leak in the process. See attached screenshot - shows memory consumption during correction of 8 files.

Done.

v1.0.2
+ multiprocessor support

14 files 4096x4096 in 14 seconds. 8)

[NKV]

Next one.
ExecuteGlobal() parts was rewritten. New charging mechanism of multi-thread processing. The code is very simple for understanding... 
and faster. 1.5 second less

[NKV]

Next one.
v.1.0.3
+Real-Time Preview. Look the movie in attachment.

How2Use:
1) Select MasterDark.
2) Add Light files. Double click at anyone Light (to open the file). Apply STF ( Ctrl+A  = AutoSTF ).
4) Define small PreView (Alt+N + paint on ImageWindow ). Activate the PreView.
5) Push Real-Time Preview(RTP) button in CosmeticCorrection Interface.
6) Enjoy.
Move Threshold sliders, Transfer Function slider and look at RTP window. Also you can move the PreView (Alt+E + drag&drop) into other parts of MainView.

Note: if you use RTP at full size window (i.e. MainView ) it can by slowly, because no matter of size RTP window - the RTP image will calculated from real pixel data of MainView image. Image size of real processed data is equal to size of PreView. Or size of MainView if PreView is not defined.

Nice! Thanks Nikolay!

Thanks Nikolay,
real time preview is a nice addition.
