I originally started this thread, July 15th, 2003 (Doom9's Forum > Announcements and Chat > General Discussion > Greyscale to RGB conversion) My objective (goal) is also stated within those threads. I also posted within >Capturing and Editing Video>Avisynth Development. Since there is a possibility that Virtualdub could serve some purpose I'm posting in this forum.
To sum, I want to covert old grayscale home videos to good quality rgb videos. I want the quality to be photo realistic or near photo realistic. (very much like monochrome photo images are converted to color) I wanted to know if software like Avisynth or Virtualdub was capable of this task. If this wasn’t possible I wanted to know if there was software within the $500.00 price range that was capable. Despite asking this question and waiting for answers I came up with some interesting information. http://www.neuraltek.com/ (Neuraltek) makes such software. They even colorize grayscale video. The proprietary software they use is called TimeBrush. They can excellently colorize 30 minutes of monochromatic video for $25,000. Well, I have about 1 hours worth of home videos that I want properly colorized. I Can’t do $50,000. This lead me further into this matter. Perhaps the method used by TimeBrush is akin to one of the following and if it isn't perhaps one of the following links can be inciteful (a stepping stone)to me or to someone more technically savy with virtualdub filters or avisynth:
1) http://www.cs.sunysb.edu/~tfwelsh/colorize/index.html and http://mrl.nyu.edu/projects/image-a...s/colorize.html
2) http://www.cad.zju.edu.cn/home/dzh/...eo%20Colorizing
3) http://www.icip03.upv.es/technical_program.htm search for subject(title) "Colorization Algorithm for Grayscale Image by Propagating Seed Pixels"
4) http://www.icme2003.com/Papers/Publ...?Sessionid=1027
(There are also very helpful links and *.pdf’s from the sites listed)
After seeing some of the program algorithms used I don’t believe this is way over my head anymore. I’m a mediocre C++ programmer and don’t know anything technical perse about video but I’m willing to learn. I believe it’s a matter of having the right tools and knowing how to use them. I’m hoping that this is were Virtualdub and or avisynth come into the picture. Can someone help me or point me in the right direction? I have to thank the moderator Wilbert for the helpful information he gave me and for pointing me in this direction.
