2D or not 2D? That is the question.

Recent work in automatic face recognition indicates that the major problem in modeling face processing is to find a meaningful representation for the faces. The difficulty arises from the often noted fact that human faces constitute a set of highly similar objects. Hence, a first constraint imposed upon a facial representation is that it must capture the subtle variations in features and config...

2D Conformal Field Theories and Holography

It is known that the chiral part of any 2d conformal field theory defines a 3d topological quantum field theory: quantum states of this TQFT are the CFT conformal blocks. The main aim of this paper is to show that a similar CFT/TQFT relation exists also for the full CFT. The 3d topological theory that arises is a certain “square” of the chiral TQFT. Such topological theories were studied by Tur...

2D or Not 2D: Bridging the Gap Between Tracking and Structure from Motion

In this paper, we address the problem of tracking an unknown object in 3D space. Online 2D tracking often fails for strong outof-plane rotation which results in considerable changes in appearance beyond those that can be represented by online update strategies. However, by modelling and learning the 3D structure of the object explicitly, such effects are mitigated. To address this, a novel appr...

Liquid-liquid phase coexistence in gold clusters: 2D or not 2D?

The thermodynamics of gold cluster anions (AuN-, N=11,...,14) is investigated using quantum molecular dynamics. Our simulations suggest that AuN- may exhibit a novel, freestanding planar liquid phase which dynamically coexists with a normal three-dimensional liquid. Upon cooling with experimentally realizable cooling rates, the entropy-favored three-dimensional liquid clusters often supercool a...

Heterodyne Holography: An Optimal and Versatile 2D Detection Scheme

Heterodyne holography is a variant of phase shifting holography in which reference and signal arms are controlled by acousto optic modulators. We will briefly describe the method and illustrate its advantages on experimental examples. OCIS codes: 090.1995: Holography: Digital holography, 040.2840: DetectorsHeterodyne Citation M.
