Abstract
A method of generating view-dependent compensated images is disclosed. A uniform image is projected on a reflective screen, resulting in a first captured image. The distribution of specular highlight is predicted according to the first captured image, thereby obtaining model parameters. Calibration images are estimated according to the model parameters and a viewing angle, and a compensated image is generated according to the calibration images at the viewing angle.
