Colorizing Images and Video by Scribbling 272
Guspaz writes "Up until now, colorizing a video or image has been a painstaking and mostly manual task. However, researchers in Israel have come up with a new way of colorizing images just by making a few scribbles. The technique works on the premise that 'neighboring pixels in space-time that have similar intensities should have similar colors,' and also allows colorization of videos by 'marking' about one in ten frames."

Only save the intensity channel and a few bits of markup and you compress the stream quite a bit.

Coming soon, new dubbing techniques will allow easy substitution of the original actors' voices and dialogue with trite teen-angst to appeal to younger generations.

If this can cut the work down to 1/10th normal it becomes plausible for the general public. While I'm no budding spielburg, I know a lot of people who might want to touch up the color quality of their wedding video.

The idea that one could color correct video with a few strokes from mspaint is staggering. Imagine if one could do this to color video, in real time... you could color-highlight an object and the computer could follow it without sensors or other pre-implanted devices, and that's not even a particularly original idea. This is awesome technology with applications probably well beyond what we see here.

I wonder how much CPU power is required, if you could do this realtime or close to it would be quite awesome, but having to make your scratches and click "apply filter" then wait for 30 seconds would not be nearly as useful/efficient.

uncompressed: 24 bits per pixel X 4 pixels = 72 bits
compressed: 8 luminance bits X 4 pixels + 8 Red bits + 8 V bits = 48 bits
100 - (48 / 72 * 100) = 33.3%!

The problems tended to be in the background, and they probably thought people's attention would stay on the foreground, but I think like many things in film you notice them subconsciously. Either the background is out of focus, in which case there are no sharp edges for the colorization to work on, or it contains a basically infinite quantity of detail as the background gets farther and farther way. Either way, it was extremely common to see uncolored areas in the background.
It was fairly common to see black-and-white paintings hanging on walls, for example. The walls would be some fairly uniform wash of plausible wall color, but nobody was going to take the time to handcolor the paintings hanging on them.
A similar problem concerned scenes with machinery in them, or anything with lots of complex, detailed motion (so that successive frames weren't similar). Thus, you'd see black-and-white printing presses operating in a colorized newspaper building...
In addition, the fact that the colorized faces, for example, were a uniformly colored wash, rather than varying in color as well as brightness, created a subtle kind of phoniness. To me, the result was the conveyance of a sort of emotional coldness. The colorized movies looked colored, but they didn't feel colored.
The exact opposite of the kind of lift you couldn't help feeling in the fifties when you saw a Technicolor spectacular--in the days when "Technicolor" meant that by golly you were watching genuine dye-imbibation prints from real color separations. Sweet as candy, but irresistable. (The effect does come through in the best DVD restorations).
