Projection-based stereoscopic wall displays allow users to immerse themselves into virtual scenes, such as architecture simulations or games. However, the usually low resolution (dpi) of such displays and slight alignment offsets between the two projectors result in a loss of detail and bad readability of textual information. We propose addressing the problem by overlaying a third projector, so...

The tachyon vacuum solution of Schnabl is based on the wedge states, which close under the star product and interpolate between the identity state and the sliver projector. We use reparameterizations to solve the long-standing problem of finding an analogous family of states for arbitrary projectors and to construct analytic solutions based on them. The solutions simplify for special projectors...

To use a projector anytime anywhere, a lot of projectorcamera based approaches have been proposed. In this paper, we focus on a focal correction technique, one of projector-camera based approaches, reduces an effect of defocus blur which occurs when a screen is located out of projector’s depth-of-field. We propose a novel method for estimating projector defocus blur on a planar screen without a...

The concept of tiled displays can be successful only if such displays are made to look like a single display perceptually. The two issues that need to be solved to achieve this goal are geometric correction and color seamlessness of images spanning across tiles. Geometric correction algorithms borrow pin-hole camera models to model projector display geometry. In this paper, we introduce an abst...

We present some ideas and demonstrations for a hybrid projectorbased rendering and display technique we call Computer Graphics Optique. Instead of partially overlapping projected images to achieve a wide-area display, we completely overlap projected images on top of each other to achieve the addition of light and color in an “optical composition buffer.” The idea is to use the optical compositi...

In this paper, we present a new fully automatic method for the geometric calibration of a video projector combining structured light projection and a RGBD camera. The projection surface does not need to be planar and is supposed to be unknown. Intrinsic and extrinsic parameter are computed without a scale factor uncertainty or any prior knowledge about the projector. Our method is based on the ...

A toolbox for the development and reduction of the dynamical models of nonequilibrium systems is presented. The main components of this toolbox are: Legendre integrators, dynamical postprocessing, and thermodynamic projector. Thermodynamic projector is the tool to transform almost arbitrary anzatz to a thermodynamically consistent model, the postprocessing is the cheapest way to improve the sol...

given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projectorcamera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces at interactive rates while simultaneously performing a series of invisible structured light projections during runtime. It supports disjoint projector-camera configurations, fas...

With the miniaturization of projection technology, the integration of tiny projection units into mobile devices is no longer fiction; therefore, such integrated projectors in mobile devices could make mobile projection ubiquitous. These phones will have the ability to project large-scale information onto any surfaces in the real world, and by doing so, the interaction space of the mobile device...
