Bloom Removal
« on: 2009 July 11 16:41:21 »
At some point a nice tool to remove the bloomed pixels and impute the appropriate pixels to repair bloomed stars is going to be a necessity?

Hi Jack,

with CAHA telescopes I make this by doing short exposures. You can make a blooming mask simply by selecting the completely saturated areas and some adjacent pixels. After that, I make an HDR composition with the short subs and put them over the blooms.

Hi Jack,

Of course yes. I've been waiting for some smart developer to implement such a nice deblooming tool. Somebody dares do it?  >:D

Don't be looking at me! I'm not that smart :) Time for someone else to start writing some components :)

I certainly cannot, but the ones I used you can set the level of pixel adu's above which are selected as blooms.  You delete these bloomed pixels and impute surrounding pixel values from the nearby background.

Hi Juan, I am a C++ developer and may be intersted to tackle the de-blooming problem. What do I need to setup a PixInsight developement enviroment on Windows? I am not commiting to any deliverable but I can start putting some thought on the problem.

That's easy. Well, sortof:

- Visual Studio 2008 (the express version may work, I haven't tried)
- PCL of the right flavor (32 or 64 bit windows)
- read the readme
- Get the Sandbox sample to compile (you'll have to muck with the sandbox project most likely. The early sample didn't compile out of the box.)
Best,

Ok you bums,

I hope this helps ;)  Free VB code for Ron Wodaski's deblomer. MaxIm DL and CCDsoft versions on the page for download.
Give Ron some credit if it really helps.

You can download the code for my Debloomer in VB 6 from the 
newastro.com web site. Go to this page for the download links:

http://newastro.com/downloads/products.php


Max
------------------------------------------------------------
I'm afraid I won't have time to interpret that code for anyone, things 
are very busy, but you are welcome to learn what you can from the code 
itself.
