Perspective cameras are the most popular imaging sensors used in computer vision. However, many application fields, including automotive, surveillance, and robotics, require the use of wide angle cameras (e.g., fisheye), which allow to acquire a larger portion of the scene using a single device at the cost of the introduction of noticeable radial distortion in the images. Affine covariant feature...
Feature extractors play an important role in different Computer Vision application domains such as registration, recognition and visual search. Different detectors have been proposed and evaluated so far assuming images taken with classic cameras. However, many operating cameras (e.g., in surveillance and automotive) are built considering a fisheye model and a preprocessing step is performed to remove...
