Where is the hot pixel filter (salt&pepper) ?
CCD's show "dark current" noise with longer exposures when warm, which shows up as isolated bright "hot pixels". In low lig...		 17 year 6 4004
Where is the hot pixel filter (salt&pepper) ? [2]
Here are a couple of examples of hot pixel background patterns from long exposures with completely different cameras, an EMCCD a...		 17 year 6 4004
Where is the hot pixel filter (salt&pepper) ? [5]
Sorry, I hit the wrong button and posted my "Hot pixel" GIFs under Unknown Title. Here they are again for those following this...		 17 year 6 4004
Where is the hot pixel filter (salt&pepper) ? [7]
That was quick work STeven. Thanks. Your documentation is also very clear and precise. A couple of comments. First a trivial one...		 17 year 6 4004
Re:Normalization Fixed [8]
That's it STeven ! With approx. the same test scene as before I  now get the following for 40-30 normalisation...		 18 year 8 5671
Re: Integrate Module Updated [6]
Good work STeven. I downloaded the new version and tested it with my low-light Philips WebCam SPC-900NC. It now resets when you ...		 18 year 8 5671
Pincushion/Barrel/Perspective Distortion Correction [6]
Yep. It now works very well. Thanks STephen. I also have Mosaic working on my home machine, so maybe that was the same memory bu...		 17 year 13 8745
Pincushion/Barrel/Perspective Distortion Correction
Roborealm's Transforms are very useful, but there are a couple that are apparently not possible - corrections for Barrel and Pi...		 17 year 13 8745
Picture Distortion [3]
Yes a manual transform would be fine STeven. My camera is mounted in a box with fixed geometry, so once I adjust the correction ...		 17 year 13 8745
Perspective, Barrel, Pincushion corrections [4]
STeven, I've discovered that you have just implemented Perspective, Barrel and Pincushion corrections. Perspective correction w...		 17 year 13 8745
Low-light integration and bright pixels [3]
Thanks Steven. First let me show what I am trying to do. I have a camera that integrates electronically (Watec WAT-120N) and am ...		 18 year 8 5671
How do I write_Images every n seconds [2]
I can use Write_Images to record every frame as a separate image, but I have a camera that integrates over time up to 10sec so t...		 17 year 2 2145
Darkfield Subtraction
OK, now I want to go even further :-) and reduce the vertical striations that are due I suppose to the structure of the C...		 18 year 2 3654

Bug & stitching together 2 cameras [9]
Hi STeven. I upgraded to the version created yesterday 11 March and now I can only see one of my two USB-2 cameras. With my old ...		 17 year 16 12444
Low-light integration and bright pixels
Image integration under low-light conditions with uncooled CCD's produces a few very bright (noisy) pixels (example). Bu...		 18 year 8 5671
Binning pixels to increase signal [8]
Thanks for confirming that STeven. Square binning is indeed generally sufficient for binning to improve images with faint featur...		 17 year 9 4217
Binning pixels to increase signal [9]
...And of course you can also do 1D-binning using the scale model in RoboRealm. Sorry, I didn't look at your Scale module caref...		 17 year 9 4217
Using more cameras. [15]
