i-Perception, 2021 The concept of optic flow, a global pattern of visual motion that is both caused by and signals self-motion, is canonically ascribed to James Gibson's 1950 book “ The Perception of the Visual World.

On Benchmarking Optical Flow [PDF]
Computer Vision and Image Understanding, 2001 Summary: Evaluating the performance of optical flow algorithms has been difficult because of the lack of ground truth data sets for complex scenes. We present a new method for generating motion fields from real sequences containing polyhedral objects and present a test suite for benchmarking optical flow algorithms consisting of complex synthetic ...

Harbor seals (Phoca vitulina) can perceive optic flow under water. [PDF]
PLoS ONE, 2014 Optic flow, the pattern of apparent motion elicited on the retina during movement, has been demonstrated to be widely used by animals living in the aerial habitat, whereas underwater optic flow has not been intensively studied so far.

Optical coherence tomography angiography of optic disc perfusion in non-arteritic anterior ischemic optic neuropathy [PDF]
International Journal of Ophthalmology, 2017 AIM: To compare the optic disc blood flow of non-arteritic ischemic optic neuropathy (NAION) eyes with normal eyes. METHODS: The optic disc blood flow densities of diagnosed non-acute phase NAION eyes (21 eyes, 14 individuals) and normal eyes (19 eyes ...

Sensor-Guided Optical Flow [PDF]
2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021 This paper proposes a framework to guide an optical flow network with external cues to achieve superior accuracy either on known or unseen domains. Given the availability of sparse yet accurate optical flow hints from an external source, these are injected to modulate the correlation scores computed by a state-of-the-art optical flow network and guide ...

Gaze strategy in the free flying zebra finch (Taeniopygia guttata). [PDF]
PLoS ONE, 2008 Fast moving animals depend on cues derived from the optic flow on their retina. Optic flow from translational locomotion includes information about the three-dimensional composition of the environment, while optic flow experienced during a rotational ...

Functional correlates of optic flow motion processing in Parkinson’s disease
Frontiers in Integrative Neuroscience, 2014 The visual input created by the relative motion between an individual and the environment, also called optic flow, influences the sense of self-motion, postural orientation, veering of gait, and visuospatial cognition.

Frontiers in Virtual Reality, 2022 We compared two measures of visually induced body sway—head motion and centre of pressure (CoP)—that were simultaneously measured while observing optic flow on a head-mounted display (HMD).
