openpiv
Performs Particle Image Velocimetry (PIV) analysis with OpenPIV. Use when extracting velocity fields from PIV image pairs, analyzing fluid dynamics or flow visualization experiments, cross-correlating interrogation windows, validating and replacing spurious PIV vectors, or computing vorticity, strain rate, and turbulence statistics from measured velocity fields.

# OpenPIV
## Overview
OpenPIV (Open Particle Image Velocimetry) analyzes fluid flow from PIV image pairs. It covers
preprocessing, cross-correlation, vector validation, outlier replacement, smoothing, and scaling to
physical units.
Targets **openpiv 0.26.1**. Synthetic checks ran on Python 3.13, NumPy 2.5.3, SciPy 1.18.1,
scikit-image 0.26.0, and Matplotlib 3.11.2. Rust was not installed; use `backend="scipy"` for the
tested path. See [review evidence](references/advanced_algorithms.md#review-sources-and-verification).
