Abstract
A method of obtaining a spatially varying bidirectional reflectance distribution function for a flat object can include using a video capture device and a light source to capture a video of an area of interest at a relatively fixed distance over the surface of the object, aligning video frame images from the captured video into a single panorama with observations from multiple light and view locations for a number of pixels, clustering the pixels into clusters by similar appearance, and fitting a bidirectional reflectance distribution function to the clusters to generate a high-resolution spatially varying bidirectional reflectance distribution function.
