Detection of Human Movement Direction Using Optical Flow Analisys on Multiple Camera Angles
Jurnal Nasional Teknik Elektro, 2021 The active movement of children poses a safety risk in the absence of adult supervision. To reduce the risk of accidents in children, an automatic detection system for the direction of children's movements is crucially needed.

Sensor-Guided Optical Flow [PDF]
2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021 This paper proposes a framework to guide an optical flow network with external cues to achieve superior accuracy either on known or unseen domains. Given the availability of sparse yet accurate optical flow hints from an external source, these are injected to modulate the correlation scores computed by a state-of-the-art optical flow network and guide ...

3D Wavelet-Based Optical Flow Estimation [PDF]
Engineering and Technology Journal, 2007 In this paper, a new algorithm for accurate optical flow estimation using discretewavelet approximation is proposed. The image sequences are always assumed tobe noiseless in the computation of optical flow, since there is always a method thatcan perform ...

An orbital energy flow and a spin flow at the tight focus
Компьютерная оптика, 2021 We have shown that a reverse energy flow (negative projection of the Poynting vector onto the optical axis) at the sharp focus of an optical vortex with topological charge 2 and left-hand circular polarization arises because the axial spin flow has a ...

Scholarpedia, 2013 Optic flow refers to the image motion of the environment projected on the retina during our movement in the world. The term was first coined by James J. Gibson and played a key role in the development of the ecological approach to visual perception, an approach that emphasizes studying human perception in the natural environment rather than in a ...
