Ascertaining the ideality of photometric stereo datasets under unknown lighting
Elisa Crabu, Federica Pes, Giuseppe Rodriguez +1
The standard photometric stereo model makes several assumptions that are rarely verified in experimental datasets. In particular, the observed object should behave as a Lambertian…

Identifying the lights position in photometric stereo under unknown lighting
A. Concas, R. Dessì, C. Fenu +2
Reconstructing the 3D shape of an object from a set of images is a classical problem in Computer Vision. Photometric stereo is one of the possible approaches. It stands on the assu…

Fast and accurate computation of orthogonal moments for texture analysis
C. Di Ruberto, L. Putzu, G. Rodriguez
In this work we describe a fast and stable algorithm for the computation of the orthogonal moments of an image. Indeed, orthogonal moments are characterized by a high discriminativ…
