Abstract
A method is described for acquiring textures without highlights or shading for use in an image-based virtual studio for TV program production. In an image-based virtual studio a virtual set is made using video components, i.e. shapes and textures from real objects. If the textures of video components have highlights or shading due to lighting, the composite images are unnatural. The proposed method uses polarized light, rotary polarized filter in front of a camera, and information on light position to remove the highlights and shading from textures, thereby enabling images to be composed under any lighting condition. The effectiveness of the method was demonstrated experimentally.
