Description

In the former study by the authors the boundary position (angle) of light and shade areas perceived on the cylinder surface was consistent with that showing the largest ratio of luminance (or illuminace) at successive two points on the cylinder surface. The apparent proportion of light and shade areas of the face was geometrically obtained by the boundary position (angle) of the light and shade areas when the face was simulated as a half cylinder and satisfactorily explained the perceived modeling. In the present study the data obtained in the previous experiments on the modelling evaluation was synthetically analyzed. As a result a multiple regression model for modelling of human face at a window was constructed with two variables of the semi-cylindrical illuminance ratio and the apparent proportion of light and shade areas.
