A model of sinusoidal grating detection based on the output of many parallel-processing spatial frequency-bandpass receptive fields is developed. The receptive fields are assumed to be of similar shape but to differ in scale and retinal location. Because the retinal image is inherently noisy due to photon noise a signal detection analysis is carried out. For a stimulus grating having a particular spatial frequency there is a most sensitive mechanism: one with a receptive field of ideal size and… CONTINUE READING
