WebThe actual FREAK algorithm also uses a cascade for comparing these pairs, and puts the 64 most important bits in front to speed up the matching process, Unfortunately, this is not yet implemented in OpenCV so it does not affect our analysis, but we expect that when this is implemented, FREAK’s matching step will speed WebThe algorithm propose a novel keypoint descriptor inspired by the human visual system and more precisely the retina, coined Fast Retina Key- point (FREAK). A cascade of binary strings is computed by efficiently comparing image intensities over a retinal sampling pattern. FREAKs are in general faster to compute with lower memory load and also ...
