Given a fixed origin o in the d-dimensional grid, we give a novel definition of digital rays dig(op) from o to each grid point p. Each digital ray dig(op) approximates the Euclide...
This paper proposes a new haptic interaction system based on optical-haptic substitution. This system combines time-modulated structured light emitted to the workspace and a mobil...
In this paper, we present a mapping of nonlinear ray tracing to the GPU which avoids any data transfer back to main memory. The rendering process consists of the following parts: ...
Modulation forensics is to detect the modulation type in wireless communications without any prior information. It nds both military and civilian applications such as surveillance...
