Global Illumination using Photon Ray Splatting
We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global...

Cooperative Location-Sensing for Wireless Networks
We present the Cooperative Location-sensing system (CLS), an adaptive location-sensing system that enables devices to estimate their position in a self-organizing manner without t...

Wavelet features for statistical object localization without segmentation
This paper describes a new technique for statistical 3{D object localization. Local feature vectors are extracted for all image positions, in contrast to segmentation in classical...
