HS Project -- Motion Estimation (Horn & Schunck)
This project explores optical flow (Horn & Schunck) and Principal Component Analysis (PCA) to estimate and characterize physiological motion in medical imaging, as a foundation for clinical tracking algorithms.
Overview
Optical flow estimation of elastic deformations, followed by spatio-temporal analysis of the displacement fields (PCA) to identify dominant motion patterns.
What the project demonstrates
Spatio-temporal analysis (PCA)
Analysis of spatio-temporal coherence and extraction of dominant motion components.

Foundation for clinical tracking
A methodological base for tracking algorithms intended for clinical applications.
