Optical flow estimation is a fundamental problem on the computer vision. Recently, a few hundreds of optical flows can compute in a real-time on a common PC system, however, to extract dense flows such as 60000 flows, the method seems to take a long computation time. In this paper, we ...
This paper presents a flexible and scalable approach to the parallelization of the computation of optical flow. This approach is based on data parallel distribution. Images are divided into several subimages processed by a software pipeline while respecting dependencies between computation stages. The pa...

This new optical flow prior is compared with previous robust priors and is incorporated into a recent, accurate algorithm for dense optical flow computation. Experiments with natural and synthetic sequences illustrate how the learned optical flow prior quantitatively improves flow accuracy and how it ...
Insects accomplish this task notably by extracting optic flow (OF) retinotopically and integrating this information across their visual field31. Our agent’s inner computation replicates this processing. The Spiking Neural Network (SNN) model tested in closed-loop within different environments consists ...
The hardware optical flow functionality in Turing GPUs helps all these use-cases by offloading the intensive flow-vector computation to a dedicated hardware engine on the GPU silicon. This frees up GPU and CPU cycles for other tasks. NVIDIA’s Optical Flow SDK exposes a new set of APIs which...
Owing to the presence of two neutrinos, the computation of the WW invariant mass is not possible. However, an associated variable, the transverse mass, mT, can be computed from the \({{\bf{p}}}_{{\rm{T}}}\) of the charged leptons and the ...
(Section 4.2), and highlight the robustness of the proposed method which can deal with very different scenes and acquisition conditions (Section 4.3). The code (computation of homologous point groups usable as input by any SfM approach) and all data used in this section are given as ...
To further reduce the computation, we can adopt a two-stage GNC process and perform three warping steps per pyramid level. This fast version (Classic+NL-Fast) has nearly the same overall performance, with a slight decline in performance on the “Urban3” sequence, which has large motions; ...
