Motion streaks improve motion detection

Vision Research, 2007
A number of studies were conducted to determine whether motion-streaks assist motion extraction, and whether a purely motion-based model could account for any observed facilitation. A 3-frame global-motion stimulus was used. Signal dots were manipulated in order to control the strength of the motion-streak.

Retinomorphic Motion Detector Fabricated with Organic Infrared Semiconductors

Advanced Science, 2023
Organic retinomorphic sensors offer the advantage of in‐sensor processing to filter out redundant static backgrounds and are well suited for motion detection.

Dogs are not better than humans at detecting coherent motion [PDF]

, 2017
The ability to perceive motion is one of the main properties of the visual system. Sensitivity in detecting coherent motion has been thoroughly investigated in humans, where thresholds for motion detection are well below 10% of coherence, i.e.

A system for learning statistical motion patterns [PDF]

, 2006
Analysis of motion patterns is an effective approach for anomaly detection and behavior prediction. Current approaches for the analysis of motion patterns depend on known scenes, where objects move in predefined ways.

Detectability of Orbital Motion in Stellar Binary and Planetary Microlenses [PDF]

, 2010
A standard binary microlensing event lightcurve allows just two parameters of the lensing system to be measured: the mass ratio of the companion to its host, and the projected separation of the components in units of the Einstein radius.

Can Transfer Entropy Infer Information Flow in Neuronal Circuits for Cognitive Processing?

Entropy, 2020
How cognitive neural systems process information is largely unknown, in part because of how difficult it is to accurately follow the flow of information from sensors via neurons to actuators.

Sensing motion using spectral and spatial analysis of WLAN RSSI [PDF]

, 2007
In this paper we present how motion sensing can be obtained just by observing the WLAN radio signal strength and its fluctuations. The temporal, spectral and spatial characteristics of WLAN signal are analyzed.
