Some of our softwares and research results are available on this page for free use. If you use one, we only ask that you please cite the appropriate publication.
Background Oriented Schlieren (BOS) Processing Software - A GUI-based, standalone software application for Windows OS for performing Background Oriented Schlieren (BOS) processing. The software uses wavelet-based optical flow analysis (wOFA) for processing, which minimizes resolution loss compared to other methods. The zip archive contains an .exe file for installation, a user guide, a set of demo images, and a PDF of a high-resolution background pattern that you can print and use freely. Please cite Schmidt and Woike (2021) if you use this software for your work.
If you work at a government lab or somewhere else that requires software be from a trusted source, you can download the uncompiled source files for the app here and compile it yourself. You should be able to install from there. Note that you will need MATLAB and the Compiler Toolbox installed in order to compile the application.
Current version: 1.4 (2/7/2024). Changes from last version: bug fixes related to image normalization.
ATLAS - a Microsoft Excel based tool for setup of a compact, self-aligning focusing schlieren system. Please cite Mejia & Schmidt (2023). The conference paper which includes instructions for using ATLAS can be downloaded here.
Line Integral Convolution (LIC) - a Matlab-based tool for line integral convolution-based visualization of vector field data, great for BOS images! The readme file in the zip archive contains instructions on usage. An example script is also included in the archive. Please cite Howard et al. (2023).
