A Graphical User Interface (GUI), providing fast and efficient workflow for evaluating and post-processing particle image velocimetry (PIV) images or results. This repository is based off of openpiv_tk_gui.

Warning:

This GUI was developed hastily for a PIV project and thus has many bugs.

Features

• Works with a wide range of image types (RGB converted to grayscale using 0.299R 0.587B 0.144G)
• Create movies (mp4, avi, non-optimized gif)
• Custom image frequencing
• Extensive image pre-processing with batch image processing (saves as 8 bit images)
• Interactive calibration
• High precision processing using iterative image deformation
• 3 subpixel estimators (gaussian, parabolic, centroid)
• Ensemble correlation with iterative image deformation
• Rectangular interrogation windows supported (50% slower than square windows)
• Average all results (excluding ensemble correlation)
• Parallel batch processing
• Extensive post-processing
• Import vectors for post-processing
• No proprietary environments
