As the popularity of digital videos increases, a large number illegal videos are
being generated and getting published. Video copies are generated by performing various
sorts of transformations on the original video data. For effectively identifying such illegal
videos, the image features that are invariant to various transformations must be extracted for
performing similarity matching. An image feature can be its local feature or global feature.
Among them, local features are powerful and have been applied in a wide variety of computer vision aplications .This paper focuses on various recently proposed local detectors and descriptors that are invariant to a number of image transformations.
