Computation of Smooth Optical Flow in a Feedback Connected Analog Network [PDF]
, 1998 In 1986, Tanner and Mead \cite{Tanner_Mead86} implemented an interesting constraint satisfaction circuit for global motion sensing in aVLSI. We report here a new and improved aVLSI implementation that provides smooth optical flow as well as global motion

Optical Flow on Moving Manifolds [PDF]
, 2014 Optical flow is a powerful tool for the study and analysis of motion in a sequence of images. In this article we study a Horn-Schunck type spatio-temporal regularization functional for image sequences that have a non-Euclidean, time varying image domain.

Combining Stereo Disparity and Optical Flow for Basic Scene Flow
, 2018 Scene flow is a description of real world motion in 3D that contains more information than optical flow. Because of its complexity there exists no applicable variant for real-time scene flow estimation in an automotive or commercial vehicle context that ...

Optical gradient flow focusing
Optics Express, 2007 This paper describes a new method for carrying out flow cytometry, which employs optical gradient forces to guide and focus particles in the fluid flow. An elliptically shaped Gaussian beam was focused at the center of a microchannel to exert radiation pressure on suspended nanoparticles that are passing through the channel, such that these particles ...

Aero-optical characterization of aircraft optical turrets by holography, interferometry and shadowgraph [PDF]
, 1980 Density variations in the aircraft boundary layer, turret wakes and shock waves create distortion of an optical wavefront through associated refractive index variations. Such effects can be observed directly through optical flow visualization.

Selectivity to approaching motion in retinal inputs to the dorsal visual pathway
eLife, 2020 To efficiently navigate through the environment and avoid potential threats, an animal must quickly detect the motion of approaching objects. Current models of primate vision place the origins of this complex computation in the visual cortex.

Nonrigid Optical Flow Ground Truth for Real-World Scenes with Time-Varying Shading Effects
, 2016 In this paper we present a dense ground truth dataset of nonrigidly deforming real-world scenes. Our dataset contains both long and short video sequences, and enables the quantitatively evaluation for RGB based tracking and registration methods.

Morphing a Stereogram into Hologram
Journal of Imaging, 2020 We developed a method to transform stereoscopic two-dimensional (2D) images into holograms via unsupervised morphing deformations between left (L) and right (R) input images.
