視覚系の空間周波数特性に基づく中心窩レンダリング

抄録

Recently, there is an increasing demand for the method of 3D rendering which achieves both reducing the processing load and keeping the quality of generated image. One of the solutions to this trade-off is ”foveated rendering”, in which rendering is simplified as far as human cannot perceive. In the most of the previous researches, they adopted foveated rendering using a heuristic and discrete evaluation which causes generated image to be unnatural for the human perception. Then we suggest the method of foveated rendering which continuously simplifies rendering based on spatial frequency response of human vision system. We experimentally show that proposed method enables to render images approximately three times as fast as maximum-resolution rendering.
