AM3F-FlowNet: Attention-Based Multi-Scale Multi-Branch Flow Network

open access: yesEntropy, 2023
Micro-expressions are the small, brief facial expression changes that humans momentarily show during emotional experiences, and their data annotation is complicated, which leads to the scarcity of micro-expression data.

Optic Flow

open access: yesScholarpedia, 2013
Optic flow refers to the image motion of the environment projected on the retina during our movement in the world. The term was first coined by James J. Gibson and played a key role in the development of the ecological approach to visual perception, an approach that emphasizes studying human perception in the natural environment rather than in a ...

Vision based experimental investigation of two-phase flow in a rising pipe [PDF]

open access: yes, 2003
Multiphase pipeline flow is very important to oil, gas and process industry. This is a class of problems where comprehensive simulations, although desirable on physical grounds, are not practical due to the large aspect ratio between the pipe length and ...

Fosquare: A novel optical hpc interconnect network architecture based on fast optical switches with distributed optical flow control [PDF]

open access: yes, 2021
Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high band-width, low latency, and low power consumption. We propose and demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control ...

Perceiving blurry scenes with translational optic flow, rotational optic flow or combined optic flow

open access: yesVision Research, 2019
Perceiving the spatial layout of objects is crucial in visual scene perception. Optic flow provides information about spatial layout. This information is not affected by image blur because motion detection uses low spatial frequencies in image structure.

Application of optical flow method in metro train speed measurement

open access: yes机车电传动, 2022
Subway speed is an important parameter of train control system. The traditional subway speed measurement methods have some defects. In this paper, a new method of subway speed measurement by using the optical flow method in image processing was explored,

No Evidence That Frontal Optical Flow Affects Perceived Locomotor Speed and Locomotor Biomechanics When Running on a Treadmill

open access: yesApplied Sciences, 2019
We investigated how the presentation and the manipulation of an optical flow while running on a treadmill affect perceived locomotor speed (Experiment 1) and gait parameters (Experiment 2).

The essential role of optical flow in the peripheral visual field for stable quiet standing: Evidence from the use of a head-mounted display. [PDF]

open access: yesPLoS ONE, 2017
It has long been thought that vision is the most essential factor in maintaining stable quiet standing compared to other sources (i.e., vestibular and somatosensory inputs) of information.
