Multimodal Vision Research Laboratory

MVRL

Research Area: Timelapse Imaging

Timelapse imaging analyzes long outdoor sequences to characterize slow environmental change, subtle plant motion, and camera geolocation from temporal patterns. It pairs with webcam and camera-network research for multi-year monitoring of landscapes and infrastructure.
