However, it has been claimed that the Gabor model does not conform to the anatomical structure of the visual system as it short-cuts the LGN and uses the 2D image as it is projected on the retina. Azzopardi and Petkov have proposed a computational model of a simple cell, which combines the responses of model LGN cells with center-surround receptive fields (RFs). They call it Combination of RFs (CORF) model.
The Gabor model has been criticized for not accurately reflecting the anatomical structure of the visual system. It bypasses the LGN and uses a 2D image as it is projected onto the retina, while Azzopardi and Petkov have proposed a computational model called CORF that incorporates responses from simplified LGN cells and center-surround receptive fields (RFs).
