This report describes a Master's thesis project to create a projector-camera system. A projector-camera system is a fairly new interface for human-computer interaction where the user can interact with projections. This report starts off by examining some previous work and then goes on to study some different solutions and approaches to the problems you face when constructing a projector-camera ...

This article addresses a question of Carl de Boor (cf. [3]): What ideal projectors are the limits of Lagrange projectors? The results of this paper answer the question in the sense that for every ideal projector P we prescribe …nitely many computations that determine whether the projector P is a limit of Lagrange projectors.

We propose an integral form of Atiah-Patodi-Singer spectral boundary conditions (SBC) and find explicitly the integral projector onto SBC for the 3-dimensional spherical cavity. After discussion of a simple example we argue that the relation between the projector and fermion propagator is universal and stays valid independently of the bag form and space dimension.

-This paper presents a new approach allowing a projector to display an undistorted image on an unknown geometry surface. In the distortion correction system, a single digital camera is used to capture the viewer’s perspective of the projection surface, and a computer is used to process the origional source image to show an undistortion image from the view position of audience. In the approach, ...

This paper describes recent developments and the current status of the Laser Diode Array Projector (LDAP) Technology. The LDAP is a state-of-the-art dynamic infrared scene projector system capable of generating high resolution in-band infrared imagery at high frame rates. Three LDAPs are now operational at the US Army Aviation and Missile Command's (AMCOM) Missile Research, Development, and Eng...

We introduce a novel framework for automatic 3D facial expression analysis in videos. Preliminary results demonstrate editing facial expression with facial expression recognition. We first build a 3D expression database to learn the expression space of a human face. The real-time 3D video data were captured by a camera/projector scanning system. From this database, we extract the geometry defor...

We analyze if entangled fermionic states can be described by a projector in the one-particle Hilbert space. A method is developed for realizing entanglement and general second quantized fermionic and bosonic fields in the framework of the fermionic projector. Our constructions are discussed with regard to decoherence phenomena and the measurement problem.

Addressing the typically time consuming adjustment of projector equipment in VR installations we propose an easy to implement projector calibration method that effectively corrects images projected onto planar surfaces and which does not require any additional hardware. For hardware accelerated 3D applications only the projection matrix has to be modified slightly thus there is no performance i...

This paper describes the application of multiple IR projector technologies to Hardware-in-the-Loop (HWIL) simulations at the US Army Aviation and Missile Command's (AMCOM) Missile Research, Development, and Engineering Center (MRDEC). Several projectors utilizing a variety of emerging technologies are currently being successfully applied within the HWIL facilities of AMCOM’s MRDEC. Projector te...
