Hi,

Slashdot has the "Story" about this - http://www.cs.huji.ac.il/~yweiss/Colorization/

I assume that to implement it one needs the color+timestamp for each drawn pixel. Is that at all possible to do in a gimp plugin?

I don't see why this should not be possible to do in a plug-in. But I don't understand your comment about the timestamp.

Nope, it refers to video. I.e. pixel neighbourhood not only in the (x,y) plane, but also in preceeding and succeeding video frames.

I only skimmed the site a little last night, but I was under the impression that the 'time' aspect had to do only with colorizing videos. (Apparently the user can stroke every 10th frame, or so, and their software would figure out the colorization need on the in-between frames.)

I could've easily be mislead by my skimming, though. ;)

I assume this to mean you need the "timing information of the stroke", similar to data needed for recognizing handwriting.

While I am not sure of the GTK low-level API for such a "capture", a plugin using such low level functions would have to re-implement the non trivial functionality of drawing the stroke (colors, brush, what-have-you ...), which is pointless.

Nope.
The "time" part of the "space time" proximity applies to animations (and movies, of course). For stativc drawings , it is all about spatial proximity.

I was asking if any of you see a better way to implement such a method in the gimp.

Hope I made myself clear this time.
