Application of optical flow method in metro train speed measurement
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,

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]
PLoS 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.

Deep Optical Flow Supervised Learning With Prior Assumptions
IEEE Access, 2018 Traditional methods for estimating optical flow use variational model that includes data term and smoothness term, which can build a constraint relationship between two adjacent images and optical flow.

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
, 2007 The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence
