Abstract
A system and method for determining rotation invariant feature descriptors for points of interest in digital images for image matching are disclosed. In one embodiment, a point of interest in each of two or more digital images is identified. Further, the digital images are transformed to change location of the point of interest in each of the digital images to a principal point. Furthermore, a rotation invariant feature descriptor is determined for the point of interest in each of the transformed digital images for image matching.
