is there color-time descriptor of videos? [closed]
I've learned that 3D-SIFT takes into consideration the edge features over time axis.
I was wondering, if there's any descriptor that describes the color features over time.
Whether it also considers edge or shape features does not matter.
the 'normal' sift feature descriptor works only on grayscale / intensity.

"over time" means ? what is your 'use-case' ? what are you trying to achieve ?
With over time I think he means that in a video sequence, local features have a certain behaviour over subsequent frames.
@berak: a nice description of what the 3D sift descriptor does. @cosmicjugend why not combine this approach with the approach of the colorsift implementation?
^^ ooooh, honestly, did not know any of it. nice paper, thanks !
thank you for all your comments. I was just wondering if there's a descriptor that does to color what 3D sift does to edges. Apparently there isn't any? I think I'll go implement one for my research purpose, which is to capture the change of general color information over time segment from videos
