Colorizing Images and Video by Scribbling

Posted by timothy on from the only-a-child-can-do-it dept.

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 colorblind! That whole site is very confusing! :P

    from looking at the before and after images, this technique looks pretty cool and will probably have applications for recoloring an image that is already color. For instance, the image where he recolors the fabric on the chair.

  4. Interactive Digital Photomontoge & Graph Cut.. by Pete+Brubaker · · Score: 5, Interesting

    This work is very similar to some work that was presented at last years siggraph using graph cut optimization titled Interactive Digital Photomontage by some researchers at the University of Washington. This stuff is really cool and has applications outside of just re-coloring black and white. For example, compositors in the film industry adjust the color composition of scenes that were filmed during the day to look like they were filmed at night. Sometimes they just need to tweak the color because the art director isnt happy with it. Other times it's because they introduced CG elements into live action scenes and they dont quite match. If they can tweak those colors interactively, without authoring masks, it is faster than re-rendering the scene and that saves money.

    Very cool stuff.

  5. application to motion video by mzs · · Score: 5, Interesting

    The site is slashdotted so I cannot read it, but i wonder if something akin to this could be used for compressing motion video. For example the intensity is encoded with currrent techniques, but instead of the color being encoded at a lower resolution, instead only a very small amount of colored points are encoded. Then during the decoding, the decoder uses an error function, intensity, and the time domain of previous and future frames to 'fill' the colors out.

  6. Colorizing examples. by ChrisUK · · Score: 5, Interesting

    I tried out their matlab code and put a few example colourings on my web page, for the interested:
