【 摘 要 】

The visual system interprets the shape of an object through a number of cues such as shading, occlusion and motion parallax. We present a simple imaging method that can provide improved perception of the surface shape of objects by enhancing shading cues. This allows physical samples such as ancient artifacts and fossils to be photographed with a conventional digital camera and then redisplayed with a new set of material properties more conducive to the interpretation of surface shape and detail 3 Pages
