In paper industry, the measurement of paper surface topography is important for paper quality control. Noncontact and fast photometric stereo overcomes the disadvantages of the tr...
Work on photometric stereo has shown how to recover the shape and reflectance properties of an object using multiple images taken with a fixed viewpoint and variable lighting cond...
Traditional photometric stereo algorithms employ a Lambertian reflectance model with a varying albedo field and involve the appearance of only one object. In this paper, we gene...

We extend photometric stereo to make it work with internet
images, which are typically associated with different
viewpoints and significant noise. For popular tourism
sites, tho...

This paper develops new theory for the optimal placement of photometric stereo lighting in the presence of camera noise. We show that for three lights, any triplet of orthogonal l...
