Don't shoot the messenger, but apparently a new algroithm that seems to be better than any colorization process I've seen...

What's more amazing is that they are documenting the algorithm in their paper...

What is also interesting is that the colors look natural, rather than an obvious paint job like some colorization processes. What I've always wondered with colorization, however, is HOW can they determine what the original color of something was? For example, an old black and white film is colorized, and the lead actress is suddenly wearing a stunning red dress. Was the dress originally red, or is there a way to figure it out, looking at the black and white images?

They don't... and there lies the problem. Besides the fact, art design, set design. lighting design and makeup are tuned specifically for black and white photography - not to mention the use of special photographic filters, etc. Even if you knew the colors that were present on the set, you wouldn't want to use them for color output. -Scott

Exactly. So, while the actress may have been wearing a green dress on the set in a particular scene, that color was not selected because it was green, but because it looked a certain way in black and white. Had the movie been filmed in Techicolor, the color choice for the dress may very well have been red (or blue, or whatever).

Fortunately the colorization process used for both movies and TV shows is a thing of the past. It was a horrible fad that came and went in the 1980s and insulted the artistic integrity of the original product that was shot in black & white, so I'm not concerned of it ever coming back that way.

Unless of course you're dealing with something that may have originally been in color and now only b/w prints exist (some of the episodes of Doctor Who come to mind)

I would think in that case that a lot of the color can be determined from still photos and those who worked on the episodes.
Movies I would purchase instantly if they were available in their correct aspect ratio:
Death Trap, Innocent Blood, The Shadow, and Remo Williams

Check out what Legend Films has been doing. I'm an opponent of colorization of black and white films, but still - wow. Examples can be found at legendfilms dot net.

Thanks for the info on the colorization process, gentlemen! Now I understand the request [demand?] Orson Welles made before he passed away, "Keep Ted Turner and his goddamn crayolas away from my movie!" [Citizen Kane]

Yes, in this instance (not colourising, but re-colouring), colouring B/W material is entirely justified. Most of the obvious candidates are the scads of British shows that had their colour VTs destroyed and only B/W copies remain (various episodes of Dr. Who, Steptoe and Son, the Goodies and Timeslip, for example), but there's plenty of U.S. telvision like this, too. Some shows that went out live (or almost-live) in colour in the U.S. weren't videotaped: the only backup copies made were B/W kinescopes. The last season (or so) of game show "What's My Line" is one example. And, some shows, such as in the case of "Dark Shadows", are like the previously-mentioned British shows where some episodes have "lost" colour episodes, with only B/W copies remaining.

It looks great but I am bit suspicious. There wasn't a single example of a well known black and white image/video that had the process applied. Every sample they had could have been color originally and converted to black and white for the purposes of their "demo." In other words, it could be a scam. I would like to see the process applied to something that we know is a black and white original, such as the video of the Hindenburg crash. -Keith
As far as I'm concerned, it's a damned shame that a field as potentially dynamic and vital as journalism should be overrun with dullards, bums, and hacks, hag-ridden with myopia, apathy, and complacence, and generally stuck in a bog of stagnant mediocrity. - Hunter S. Thompson, 1958, from cover letter he wrote for a newspaper job.

It seems to be incomplete. Posted Image You need mex.h, not supplied, and probably Matlab base software too.
