High-resolution velocity determination from particle images via neural networks with optical flow velocimetry regularization
Particle image velocimetry (PIV) and optical flow velocimetry (OFV) are important velocity
measurement methods in the field of fluid dynamics. Nevertheless, the conventional cross
correlation-based PIV method is beset by diminished resolution, while the OFV method
exhibits computational sluggishness and susceptibility to noise. These constraints have
somewhat delimited the applicability of PIV and OFV techniques. Recent attempts have
introduced deep learning-based methods for analyzing PIV images, offering high-resolution …
