The Reverse Projection Correlation Principle for Depth from Defocus
In this paper, we address the problem of finding depth from defocus in a fundamentally new way. Most previous methods have used an approximate model in which blurring is shift in...

Shadow walking: An unencumbered locomotion technique for systems with under-floor projection
When viewed from below, a user’s feet cast shadows onto the floor screen of an under-floor projection system, such as a sixsided CAVE. Tracking those shadows with a camera provi...

Modeling Ontological Concepts of Motions with Two Projection-Based Spatial Models
To model human concepts of motions is essential for the development of the systems and machines that collaborate with ordinary people on spatiodynamic tasks. This paper applies two...

3D Forward and Back-Projection for X-Ray CT Using Separable Footprints
The greatest impediment to practical adoption of iterative methods for X-ray CT is the computation burden of cone-beam forward and back-projectors. Moreover, forward and back-proje...

Macro and micro view on steady states in state space
This paper describes visualization of chaotic attractor and elements of the singularities in 3D space. 3D view of these effects enables to create a demonstrative projection about r...
