Neat BBC video color recovery research

Unscrambling an army of colours, reports The Guardian on the BBC's forthcoming screening of a colour-restored episode of the WWII sitcom Dad's Army. Not seen for 40 years and lost in its original PAL video colour format, it existed only as an archive on 16mm b&w film. However, the Colour Recovery Working Group found a way to recover the colour information from "chroma dots": pattern artefacts on the b&w representing unfiltered colour signal. Techie details here and here.

Household of imaging geeks here. Gleefully sharing the post with our signal-processing pals and passing it along to coworkers. Imaging science is hot.

Naturally, Doctor Who figures into this (linked in linked article). There's also a related restoration technique known as VidFIRE that has been used on both programmes as well as potentially applicable to many others in the BBC archives which only exist as telerecordings. Too bad it isn't something that works with North American NTSC. I assume this process is much less expensive than the usual colorization technology.

I really don't get why The Doctor hasn't just set up a Tivo in the past somewhere already.

[From the Guardian link] The descrambling process is akin to turning an omelette back into an egg. Oh, I get it. No need to read further. Thank you Guardian.
