Sequential Monte Carlo tracking by fusing multiple cues in video sequences [PDF]

, 2007
This paper presents visual cues for object tracking in video sequences using particle filtering. A consistent histogram-based framework is developed for the analysis of colour, edge and texture cues.

Coping With Multiple Visual Motion Cues Under Extremely Constrained Computation Power of Micro Autonomous Robots

IEEE Access, 2020
The perception of different visual motion cues is crucial for autonomous mobile robots to react to or interact with the dynamic visual world. It is still a great challenge for a micro mobile robot to cope with dynamic environments due to the restricted ...

The Effects of Augmented Reality Visual Cues on Turning in Place in Parkinson's Disease Patients With Freezing of Gait

Frontiers in Neurology, 2020
Background: Turning in place is particularly bothersome for patients with Parkinson's disease (PD) experiencing freezing of gait (FOG). Cues designed to enforce goal-directed turning are not yet available.Objectives: Assess whether augmented reality (AR)

Investigating visual analogies for visual insight problems [PDF]

, 2010
Much research has focused on the impact of analogies in insight problem solving, but less work has investigated how the visual analogies for insight are actually constructed.

Visual form Cues, Biological Motions, Auditory Cues, and Even Olfactory Cues Interact to Affect Visual Sex Discriminations

i-Perception, 2011
Johnson and Tassinary (2005) proposed that visually perceived sex is signalled by structural or form cues. They suggested also that biological motion cues signal sex, but do so indirectly.

Referential and visual cues to structural choice in visually situated sentence production [PDF]

, 2012
We investigated how conceptually informative (referent preview) and conceptually uninformative (pointer to referent’s location) visual cues affect structural choice during production of English transitive sentences.

An investigation of visual cues used to create and support frames of reference and visual search tasks in desktop virtual environments [PDF]

, 2002
Visual depth cues are combined to produce the essential depth and dimensionality of Desktop Virtual Environments (DVEs). This study discusses DVEs in terms of the visual depth cues that create and support perception of frames of references and ...

Multimodal Cues Do Not Improve Predator Recognition in Green Toad Tadpoles

Animals, 2022
The anti-predator behaviour of green toad (Bufotes balearicus) tadpoles was investigated by exposing them to only the visual or chemical cues, or a combination of both, of a native predator, southern hawker Aeshna cyanea.

­­Effect of multimodal cues from a predatory fish on refuge use and foraging on an amphidromous shrimp [PDF]

PeerJ, 2021
Background Prey can alter their behavior when detecting predator cues. Little is known about which sensory channel, number of channels, or the interaction among channels that shrimp species use to evaluate the threat from predators.
