| Research Abstract |
Photometric stereo method recovers the shape and reflectance of an object along with lighting conditions, minimizing the differences between input images and synthesized images under the recovered parameters. Several techniques has been employed and/or invented to overcome difficulties of the problem, and more than 100 image sets are successfully processed. Typical calculation time is about a minute for 30 images with 20, 000 effective pixels using a desktop PC.
