Hi there,
This post may be mainly interesting for the german speaking folks - sorry.
I have written a research (diplomathesis) about keying and Colorspace converisions.
You can find more information on it at www.HL-insi.de . The website is in English, although the thesis itself is available in german only.
Here is a little excerpt about what the thesis is all about:
Suggestions for an improved workflow in the film post-production, especially keying when it comes to preserving the qualtiy of filmdata. This means especially the nature of different colorspaces such as CIE, RGB and YCbCr as well as colorspace conversions and subsampling.
The analysis of the current keying-software solutions and presentation of new keying approaches.
In my research I am taking a close look at keying software offered by Ultimatte, Primatte and Discreet and am analysing new keying approches like Z-Keying or keying in front of a reflective screen.
I am looking forward to your feedback.
cheers,
Helmut
P.S.
I have posted this also in the AE and Flame/Inferno forum, because AE users may not stumble upon this post in a Combustion forum and vice versa. Sorry for that....
