Fluere is a graphical program package for Particle Image Velocimetry (PIV), perform velocimetry analysis on sets of digital image data.
The goal of the project is to provide researchers and educators with high-quality velocimetry program that incorporates the latest advancements in PIV processing, while having complete knowledge of the algorithms used.
Fluere Features:
1. Highly optimized correlation using the FFTW library
2. Multi-pass, multi-grid, discrete window offset and image deformation algorithms
3. Multiple peak detection ability
4. Outlier detection and replacement
5. Vorticity calculation
6. Statistics calculation (averages and fluctuations)
7. Robust batch processing support
8. Extensive documentation
9. Direct export ability to Tecplot-compatible data files
10. Full access to the source code through the GPL license
