Abstract—In this paper, the synopsis of local invariant interest point detectors, their working, advantages, disadvantages and recent trends are presented. The features detector extracts the features from the image, e.g., a corner, blob or edge detector. A features detector is said to be invariant if under a certain family of transformations if its value does not change when a transformation from this family is applied to its argument. The characteristics of this detector are robustness, repeatability, accuracy, generality, efficiency, quantity etc. Some of the feature detectors are SIFT SURF, FAST, BRISK, ORB and HCD. These descriptors are compared according to their average processing time per frame.

Index Terms—Feature, SURF, FAST, ORB, HCD
