Raw Synthetic PIV Data With Exact Optical Flow

Synthetic Particle Image Velocimetry (PIV) data generated by PIV Image Generator Software. Which is a tool that generates synthetic Particle Imaging Velocimetry (PIV) images with the purpose of validating and benchmarking PIV and Optical Flow methods in tracer based imaging for fluid mechanics (Mendes et al., 2020). This data was generated with the following parameters: image width: 665 pixels; image height: 630 pixels; bit depth: 8 bits; particle radius: 1, 2, 3, 4 pixels; particle density: 15, 17, 20, 23, 25, 32 particles; delta x factor: 0.05, 0.1, 0.15, 0.2, 0.25 %; noise level: 1, 5, 10, 15; out-of-plane standard deviation: 0.01, 0.025, 0.05; flows: rankine uniform, rankine vortex, parabolic, stagnation, shear, decaying vortex
