In contrast, the scene flow is a 3D motion field of the dynamic scene between two frames. Traditional approaches for the estimation of optical flow and scene flow usually leverage the variational technique, which can be solved as an energy minimization process.
WebMar 19, 2024 · Owing to the lack of feature information in the occluded areas, the smoothing term is often used to deduce the optical flow in the occluded area, but it results in over-smoothing optical flow. The image-adaptive, isotropic diffusion [ 19 ], anisotropic diffusion [ 20 ], and isotropic diffusion with non-quadratic regularizes [ 17 ] are proposed ...
