TL;DR: A significant novelty is introduction of a new VOT short-term tracking evaluation methodology, and introduction of segmentation ground truth in the VOT-ST2020 challenge – bounding boxes will no longer be used in theVDT challenges.

Specularities Reduce Ambiguity of Uncalibrated Photometric Stereo
Ondrej Drbohlav,Radim Sara +1 more
TL;DR: It is shown that if object reflectance is a sum of Lambertian and specular terms, the ambiguity reduces into a 2dof group of transformations (compositions of isotropic scaling, rotation around the viewing vector, and change in coordinate frame handedness).

Unambiguous determination of shape from photometric stereo with unknown light sources
Ondrej Drbohlav,Radim Sara +1 more
TL;DR: It is verified that applying the first constraint together with the integrability constraint results in bas-relief ambiguity, while application of the second constraint on integrable normals reduces the ambiguity to convex/concave ambiguity.
