Filtered Stochastic Shadow Mapping Using a Layered Approach [PDF]

Computer Graphics Forum, 2015
AbstractGiven a stochastic shadow map rendered with motion blur, our goal is to render an image from the eye with motion‐blurred shadows with as little noise as possible. We use a layered approach in the shadow map and reproject samples along the average motion vector, and then perform lookups in this representation.

Tracking a single pigeon using a shadowing filter algorithm [PDF]

Ecology and Evolution, 2017
AbstractMiniature GPS devices now allow for measurement of the movement of animals in real time and provide high‐ quality and high‐resolution data. While these new data sets are a great improvement, one still encounters some measurement errors as well as device failures.

Design of Shadow Filter Using Low-Voltage Multiple-Input Operational Transconductance Amplifiers [PDF]

Applied Sciences
This paper introduces shadow filters that employ multiple-input operational transconductance amplifiers (MI-OTAs) as the active component. Two configurations of shadow filters are proposed.

Soft bilateral filtering volumetric shadows using cube shadow maps [PDF]

PLOS ONE, 2017
Les ombres volumétriques augmentent souvent le réalisme des scènes rendues en infographie. Les techniques d'ombres volumétriques typiques ne fournissent pas un effet de transition en douceur en temps réel avec une conservation sur la netteté des limites.

Diffraction perception in L-shaped rooms using virtual reality [PDF]

EURASIP Journal on Audio, Speech, and Music Processing
Outside of shoebox rooms, acoustic diffraction phenomena are present and can influence important aspects of auditory perception, such as localisation.

Aerosol optical depth retrievals in central Amazonia from a multi-filter rotating shadow-band radiometer calibrated on-site [PDF]

Atmospheric Measurement Techniques, 2019
Extraterrestrial spectral response calibration of a multi-filter rotating shadow band radiometer (MFRSR) under pristine Amazonian Forest atmosphere conditions was performed using the Langley plot method. The MFRSR is installed in central Amazonia as part

FUZZY IMPLICATIVE FILTERS OF BE-ALGEBRAS BASED ON THE THEORY OF FALLING SHADOWS [PDF]

Facta Universitatis, Series: Mathematics and Informatics, 2018
Based on the idea of falling shadows and fuzzy sets, the notion of a falling fuzzy implicative filter of a BE-algebra is introduced. Relations between fuzzy implicative filters and falling fuzzy implicative filters are provided.

Implementation of arbitrary real-valued correlation filters for the shadow-casting incoherent correlator

, 1996
International audienceWe describe an incoherent correlator, based on the shadow-casting principle, that is able to implement any real-valued linear correlation filter.
