On Parameters of Nonlinear Scalar Dynamics from Video: Invariants, Calibration, and Identifiability
Physical parameter estimation from video aims to recover the parameters of a known family of governing dynamical equations from pixel observations. Existing identifiability theory for this setting has focused on linear time-invariant (LTI) second-order systems, leaving open what can be identified for nonlinear scalar d …
