Sparse optical flow regularisation for real-time visual tracking [PDF]

open access: yes, 2013
Optical flow can greatly improve the robustness of visual tracking algorithms. While dense optical flow algorithms have various applications, they can not be used for real-time solutions without resorting to GPU calculations.

Double-Cycle Alternating-Flow Diode Pumped Potassium Vapor Laser

open access: yesPhotonics
A novel double-cycle alternating-flow diode-pumped potassium vapor laser is proposed, theoretically modeled and simulated. The results show that the optical-to-optical efficiency of the laser increases with increasing gas flow rates, although at high ...

Direct Optical-Flow-Aware Computational Framework for 3D Reconstruction

open access: yesIEEE Access, 2019
In this paper, a direct computational method is presented which combines optical flow and structure from motion (SfM) by putting the SfM problem in the framework of optical flow estimation. In other word, the optical flow is reparametrized in term of the

Optical Flow in Mostly Rigid Scenes

open access: yes, 2017
The optical flow of natural scenes is a combination of the motion of the observer and the independent motion of objects. Existing algorithms typically focus on either recovering motion and structure under the assumption of a purely static world or ...

Optical Flow on Evolving Surfaces with an Application to the Analysis of 4D Microscopy Data [PDF]

open access: yes, 2013
We extend the concept of optical flow to a dynamic non-Euclidean setting. Optical flow is traditionally computed from a sequence of flat images. It is the purpose of this paper to introduce variational motion estimation for images that are defined on an ...

Fast Multi-frame Stereo Scene Flow with Motion Segmentation

open access: yes, 2017
We propose a new multi-frame method for efficiently computing scene flow (dense depth and optical flow) and camera ego-motion for a dynamic scene observed from a moving stereo camera rig.

Complementary Optic Flow [PDF]

open access: yes, 2009
We introduce the concept of complementarity between data and smoothness term in modern variational optic flow methods. First we design a sophisticated data term that incorporates HSV colour representation with higher order constancy assumptions, completely separate robust penalisation, and constraint normalisation.

On event-based optical flow detection

open access: yesFrontiers in Neuroscience, 2015
Event-based sensing, i.e. the asynchronous detection of luminance changes, promises low-energy, high dynamic range, and sparse sensing. This stands in contrast to whole image frame-wise acquisition by standard cameras. Here, we systematically investigate
