Image-Based Experimental Measurement Techniques to Characterize Velocity Fields in Blood Microflows
Frontiers in Physiology, 2022 Predicting blood microflow in both simple and complex geometries is challenging because of the composition and behavior of the blood at microscale. However, characterization of the velocity in microchannels is the key for gaining insights into cellular ...

Correlation image velocimetry: a spectral approach [PDF]
Applied Optics, 2002 A method, believed to be new, is introduced to evaluate displacement fields from the analysis of a deformed image compared with a reference image. In contrast to standard methods, which determine a piecewise constant displacement field, the present method gives direct access to spectral decomposition of the displacement field.

Feature Tracking Velocimetry Applied to Airborne Measurement Data from Murg Creek
E3S Web of Conferences, 2018 A new image feature tracking velocimetry is presented and tested on airborne video data available from a previous study at Murg Creek (Canton Thurgau, Switzerland). Here, the seeded flow scenery had been recorded by an off-the-shelf action camera mounted

Image processing technique for hydraulic application
Труды Института системного программирования РАН, 2018 In this paper, we present techniques Surface Flow Image Velocimetry (SFIV) that is a practical extension of Particle Image Velocimetry method (PIV). In particular, this technique is to evaluate the behavior on the surface flow for complex flow.

Defocusing digital particle image velocimetry and the three-dimensional characterization of two-phase flows [PDF]
, 2002 Defocusing digital particle image velocimetry (DDPIV) is the natural extension of planar PIV techniques to the third spatial dimension. In this paper we give details of the defocusing optical concept by which scalar and vector information can be ...

Digital particle image velocimetry [PDF]
Experiments in Fluids, 1991 Digital particle image velocimetry (DPIV) is the digital counterpart of conventional laser speckle velocitmetry (LSV) and particle image velocimetry (PIV) techniques. In this novel, two-dimensional technique, digitally recorded video images are analyzed computationally, removing both the photographic and opto-mechanical processing steps inherent to PIV
