Object recognition using graph spectral invariants
Graph structures have been proved important in high level-vision since they can be used to represent structural and relational arrangements of objects in a scene. One of the probl...

Building World Models by Ray-Tracing within Ceiling-Mounted Positioning Systems
Context-aware computing in location-aware environments demands the combination of real world position with a computational world model to infer context. We present a novel approach...

Trace Representation of Legendre Sequences
In this paper, a Legendre sequence of period p for any odd prime p is explicitely represented as a sum of trace functions from GF(2n) to GF(2), where n is the order of 2 mod p.

Spectrally optimal sampling for distribution ray tracing
Nonuniform sampling of images is a useful technique in computer graphics, because a properly designed pattern of samples can make aliasing take the form of high-frequency random n...
