ZIT: Zooplankton Image Tool for 2d rendering of biological locomotion

It turns motion-over-time into a single composited frame using OpenCV MOG2 + contour filtering and even provides a 5x5 parameter-sweep grid to brute-force good thresholds. Practical and focused: usable from the CLI or via poetry, great for batch processing lab videos — but it’s an application of classic CV tricks rather than new tracking or learning-based innovation.
