A Spherical Model Based Keypoint Descriptor and Matching Algorithm for Omnidirectional Images
Omnidirectional images generally have nonlinear distortion in radial direction.Unfortunately, traditional algorithms such as scale-invariant feature transform (SIFT) and Descriptor-Nets (D-Nets) do not work well in matching omnidirectional images just because they are incapable of hot pink softball glove dealing with the distortion.In order to solv
