In this study, we investigated the use of successive omnidirectional appearance manipulation for the cooperative control of multiple projector camera systems. This type of system comprises several surrounding projector camera units, where each unit projects illumination independently onto a different aspect of a target object based on feedback from the projector cameras. Thus, the system can fa...

We present a robust calibration method for aligning a camera-projector system to multiple planar surfaces. Unlike prior work, we do not recover the 3D scene geometry, nor do we assume knowledge of projector or camera position. We recover the mapping between the projector and each surface in three stages. In the first stage, we recover planar homographies between the projector and the camera thr...

We study embeddings of continuous dynamical systems in larger dimensions via projector operators. call this technique PEDS, projective embedding systems, as the stable fixed point dynamics are recovered projection from higher dimensional space. In paper we provide a general definition and prove that for particular type operator rank-1, uniform mean field projector, equations motion become appro...

This paper presents an approach of using a steerable projector and camera unit in order to augment instrumented environments with projected virtual objects. The environment appears to be covered with a kind of invisible virtual layer on which images, texts, videos, computer desktops and other virtual objects can be placed. By steering the projector beam on particular surfaces the objects placed...

In this work, a reflectarray is proposed to be used as probe of reduced and portable compact-antenna-test range for 5G new radio devices. The works at 28 GHz produces quiet zone in the near-field region antenna. Considering that specifications are established terms amplitude phase ripple, synthesis technique presented optimize near field Fresnel with constraints. based on generalized intersecti...

We present a novel method for 3D shape acquisition, based on mobile structured light. Unlike classical structured light methods, in which a static projector illuminates the scene with dynamic illumination patterns, mobile structured light employs a moving projector translated at a constant velocity in the direction of the projector’s horizontal axis, emitting static or dynamic illumination. For...

The aim of this thesis to perform geometric self calibration of a projector camera system using only a smartphone and a small projector. The developed system is capable of performing Structured Light Scanning with off-the-shelf devices, namely a Nokia N900 smartphone and an Optoma PK 320 pico projector. We decouple the projector from the smartphone, which is our computational device and our cam...

Quantum measurements can be generalized to include complex quantities. It is possible relate the quantum weak values of projection operators third order Bargmann invariants. The argument value becomes, up a sign, equal Berry's phase associated with three state vectors. In case symmetric informationally complete, positive operator valued measures (SIC-POVMs), this relation takes particularly sim...

where X is a known n × p model matrix, the vector y is an observable ndimensional random vector, β is a p × 1 vector of unknown parameters, and ε is an unobservable vector of random errors with expectation E(ε) = 0, and covariance matrix cov(ε) = σV, where σ > 0 is an unknown constant. The nonnegative definite (possibly singular) matrix V is known. In our considerations σ has no role and hence ...

Graph embedding techniques for bounding eigenvalues of associated matrices have a wide range of applications. The bounds produced by these techniques are not in general tight, however, and may be off by a log n factor for some graphs. Guattery and Miller showed that, by adding edge directions to the graph representation, they could construct an embedding called the current flow embedding, which...
