ljubicicrobert/SSIMS-Flow ? reverse-engineered prompt

Build me a Windows desktop app for image velocimetry that helps estimate open channel flow from fixed camera or drone videos.

I want a simple GUI where I can create or open a project, choose a Python interpreter, load a video, and step through the full workflow without needing the command line. The app should unpack videos into frames, handle camera calibration and distortion removal, stabilize and orthorectify the images, let me filter or enhance frames, pick the best frame sequence for velocity analysis, and then run dense optical flow to estimate the surface velocity field. From there, it should estimate discharge when bathymetry data is available, and also be able to turn image frames back into a video.

Please make it feel like a practical workbench for researchers, with clear status messages, progress feedback, and a clean way to save results inside each project folder. If anything is unclear, look up current docs online if you need to.
