Abstract
We propose a visual appearance simulation method for exhibited objects such as direction boards considering both eyesight and visual angles of viewers. Our method consists of two steps: optical simulation step and neural simulation step. In optical simulation step, first, the visual angle of the actual exhibited objects and of the images on computer monitors are matched. Then, we generate blurred image to simulate viewers' eyesight by using Gaussian filter. In neural simulation step, we simulate image contrast enhancement due to lateral inhibition by applying a convolution filter with DOG distribution. Appropriate parameters of both filters are based on experimental measurements, which are corresponding to viewers' eyesight. Our method can simulate visual appearance of various exhibited objects which is viewed from arbitrary distance with arbitrary eyesight.
