Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0028] In order to quantitatively describe the input-output characteristics of the retinal ganglion cell receptive field, the present invention adopts a double Gaussian difference model (DOG model) to describe the traditional receptive field of the ganglion cell with concentric overlapping circular areas of different sizes. central and peripheral areas. However, studies have shown that there is a large-scale disinhibition area in the traditional receptive field. Based on the DOG model, a three-Gaussian model is proposed, and a third Gaussian kernel is added to represent a large-scale disinhibition area.
[0029] Biological studies have shown that the subjective brightness of the human eye is a logarithmic function of the ...
