Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

This comprehensive literature review was performed based on a search of peer-reviewed published papers relevant to optical coherence tomography angiography (OCTA) according to our current knowledge, ...

This paper describes OpenOpticalFlow, an open source optical flow program in Matlab for extraction of high-resolution velocity fields from various flow visualization images. This program is a useful ...

This video shows Focus 2.0 optical flow meter from Photon Control. The flow meter is designed for gas flaring applications, using Laser 2 Focus Velocimetry Technology. It enables oil and gas companies ...

The way we perceive the visual motion of objects as we move is a phenomenon called 'optic flow.' Now, Brown University researchers have discovered that optic flow helps us to walk. They've used ...
