Researchers have developed a new method for reconstructing wind-driven vegetation in monocular video, addressing the challenge of unobservable motion along the viewing direction and lack of static reference points. The approach replaces directly learned deformation fields with a physically parameterized deformation prior, utilizing a damped harmonic oscillator for each rigid part. This prior is integrated using a differentiable RK4 method and supervised photometrically, aiming to recover motion rather than just optimize photometric consistency. While the method shows improved temporal extrapolation and performance on unseen wind speeds, it comes at the cost of appearance fidelity on in-distribution views, and parameter recovery, particularly for damping, remains weak.
