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."

I'm sure there are good reasons for the JPEG/MPEG method, and I'd be a bit surprised if the groups in question didn't think of this possibility, but I still think it should theoretically give better results (at the cost of higher complexity and computational requirements).

Interesting. Mods are funny people, I love'em. Such unpredictable little things, aren't they?

A colour image is desaturated compared to a B&W image? Hello McFly?
Please look up saturation in regard to colour.
Hint: Try raising the saturation of a colour image in photoshop or gimp (ctrl-u in photoshop). Observe. Then try using the "Desaturate" function and see what you get.
