WebImage processing by the eye is treated as a classical example of concatentated linear filters followed by a sampling operation. The first filter is optical and is characterized by an optical point-spread function. The second filter is neural and is characterized by the neural point-spread function, which is shown to be related to the receptive fields of retinal neurons. … WebStructure of human eye The human eye is a spherical structure which fits in the eye socket in the skull bone.
