Features & Segmentation

I am reading some articles about segmentation (how to combine both color and depth information) and feature extraction (knowing more about SIFT, SURF, NARF, etc). Although the last reference is out of scope, it gives some ideas about the use of Microsoft Kinect, Features and how to do feature matching.
