Arbitrary Object Relighting with Complex Pattern Texture for Reducing Eye Fatigue and Improving Perceived Depth

We present a novel method to relight arbitrary object with complex pattern texture image for reducing eye fatigue and improving perceived depth for watching the 3D display system. We estimate the light source direction and relight a texture image of a single 3D model under arbitrary unknown illumination conditions. We create a virtual irradiance sphere to detect the light source direction from a given illuminated texture image using both normal vector mapping and improved weighted bilinear interpolation. We then induce a relighting equation with estimated ambient and diffuse intensity. Our approach reduce visual load and improve visual performance in tasks for watching 3D displays.
