Hair plays an important role in recognizing a person, for instance, in an application of facial surgery simulation. This paper is concerned with a method for constructing a 3D hair model from photographs and a 3D head model de rived from CT data that do not contain hair. Our objective is to investigate a method with a small number of photographs as low as three, the minimum number. Since we employ a sculpture technique for hair mod eling, the resulting hair shape is more angular or rugged as the number is reduced. We propose here a new smoothing scheme based upon Bezier curves. We investigated three alternatives: use of seven, five, and three photographs. It was found that a satisfactory result is obtainable with five photographs. With three photographs, small difference be tween the actual and the resulting model existed, although it may be tolerable for some applications.
