Various techniques to detect and describe features in an image — Part 2

In continuation to the previous post, let continue other techniques for feature detection and description.

FAST Algorithm for corner detection

We saw several feature detectors and many of them are really good. But when looking from a real-time application point of view, they are not fast enough. One best example would be SLAM (Simultaneous Localization and Mapping) mobile robot which have limited computational resources.
