متن کاملOptical Flow Fields: Dense Correspondence Fields for Highly Accurate Large Displacement Optical Flow Estimation
Modern large displacement optical flow algorithms usually use an initialization by either sparse descriptor matching techniques or dense approximate nearest neighbor fields. While the latter have the advantage of being dense, they have the major disadvantage of being very outlier-prone as they are not designed to find the optical flow, but the visually most similar correspondence. In this artic...
متن کاملDense Point Trajectories by GPU-Accelerated Large Displacement Optical Flow
Dense and accurate motion tracking is an important requirement for many video feature extraction algorithms. In this paper we provide a method for computing point trajectories based on a fast parallel implementation of a recent optical flow algorithm that tolerates fast motion. The parallel implementation of large displacement optical flow runs about 78× faster than the serial C++ version. This...
متن کاملLarge Displacement Optical Flow with Adaptive Feature Match
This paper presents an accurate large displacement optical flow estimation approach by adaptively integrate the local feature match. Despite coarse-to-fine warping approach can handle large displacement optical flow; however, there is inherent limit for small object with large motion. And recently integration of feature match to the variational framework has relaxed the limit, but raised anothe...
متن کاملNonlinear Variational Method for Optical Flow Computation
We present a new method for optical flow computation based on the minimization of a non-quadratic functional. The solution of the obtained nonlinear differential equations is done with a time dependent approach leading to the successive solutions of linear systems. This new method allows to compute optical flow fields while insuring a unique solution and preserving the flow discontinuities. Thi...
