SPHORB

The SPHORB (Spherical ORB) package is an implementation in OpenCV of the algorithm introduced in "SPHORB: A Fast and Robust Binary Feature on the Sphere" by Zhao et al. This algorithm is designed to detect and describe the features for spherical panoramic images, which are more and more easily obtained for common users. Based on a nearly regular hexagonal grid parametrization of the sphere - geodesic grid, we can adopt the planar ORB features to the spherical domain and achieve satisfactory performance.
