Non-Line-of-Sight Surface Reconstruction Using the Directional Light-Cone Transform
Computer Vision and Pattern Recognition, 2020We propose a joint albedo–normal approach to non-line-of-sight (NLOS) surface reconstruction using the directional light-cone transform (D-LCT). While current NLOS imaging methods reconstruct either the albedo or surface normals of the hidden scene, the ...

In this chapter we shall embark upon an axiomatization of Einstein-Weyl causality on a set M consisting of points in the sense of Euclidean geometry.1 Our aim is to investigate the mathematical consequences of Einstein-Weyl causality at the local level, and we therefore assume that M carries no predefined mathematical structure.

Uncertainty Principles and Light Cones
Journal of Fourier Analysis and Applications, 2015For a non-degenerate quadratic form \(q\) of arbitrary signature, this paper proves the uncertainty principle of Hardy type which constrains the possibility to localize a distribution and its Fourier transform near the cone where \(q=0\). It is noticed that the results presented in this article are known for positive definite \(q\).

Measuring Light-Cone Singularities
Physical Review D, 1970The scaling behavior observed in deep-inelastic electron scattering is related to the structure of the electric current commutation function in position space. We show that scaling is assured when that object has the following form, which is also consistent with Regge behavior: ${i〈p|[{j}^{\ensuremath{\mu}},(x), {j}^{\ensuremath{\nu}}(0)]|p〉=[{g ...

In classical physics differential equations are used to describe the evolution of a physical system. A well-defined problem must then include a set of initial values. In the quantum case, the corresponding information is provided when canonical commutators are specified.

In this workshop, together with beautiful experimental work, we have heard reports of a lot of theoretical progress, some exciting, some puzzling, perhaps asking more questions than answering them. We have also seen that some problems which were around twenty-five years ago, like the problem of condensates and the vacuum in light-cone field theory, are

Discretized Light-Cone Quantization
1996The method of Discretized Light-Cone Quantization is reviewed in simple terms. Emphasis is put on how one should define a Hamiltonian, and on periodic boundary conditions. Some numerical results for one and for three space dimensions are compiled. The challenges and the virtues of the method are discussed in short.
