PIV-FlowDiffuser:Transfer-learning-based denoising diffusion models for PIV
CoRRDeep learning algorithms have significantly reduced the computational time and improved the spatial resolution of particle image velocimetry~(PIV). However, the models trained on synthetic datasets might have a degraded performance on practical particle images due to domain gaps.

Variational 3D-PIV with sparse descriptors [PDF]
Measurement Science and Technology, 2018 Abstract 3D particle imaging velocimetry (3D-PIV) aims to recover the flow field in a volume of fluid, which has been seeded with tracer particles and observed from multiple camera viewpoints. The first step of 3D-PIV is to reconstruct the 3D locations of the tracer particles from synchronous views of the volume.
