Optical flow versus retinal flow as sources of information for flight guidance [PDF]
The appropriate description is considered of visual information for flight guidance, optical flow vs. retinal flow. Most descriptions in the psychological literature are based on the optical flow.

Im2Flow: Motion Hallucination from Static Images for Action Recognition
Existing methods to recognize actions in static images take the images at their face value, learning the appearances---objects, scenes, and body poses---that distinguish each action class.

Estimating Sensor Motion from Wide-Field Optical Flow on a Log-Dipolar Sensor [PDF]
Log-polar image architectures, motivated by the structure of the human visual field, have long been investigated in computer vision for use in estimating motion parameters from an optical flow vector field. Practical problems with this approach have been:

Self-Supervised Pre-Training for Optical Flow Estimation via Contrastive Learning
To address the issues of dataset dependency and correlation volume redundancy in optical flow estimation, contrastive learning is introduced to build a self supervised optical flow framework.

Optical Flow Refinement using Reliable Flow Propagation
This paper shows how to improve optical flow estimation by considering a neighborhood consensus strategy along with a reliable flow propagation method. Propagation takes advantages of reliability measures that are available from local low level image features.

Influence of phosphorus doping on hydrogen content and optical losses in PECVD silicon oxynitride [PDF]
PECVD Phosphorus-doped silicon oxynitride layers (n=1.5) were deposited from N2O, 2%SiH4/N2, NH3 and 5%PH3/Ar gaseous mixtures. Chemical bonds were determined by Fourier transform infrared spectroscopy. N–H bond concentration of the layers decreased from

Horn-Schunck Optical Flow with a Multi-Scale Strategy
The seminal work of Horn and Schunck is the first variational method for optical flow estimation. It introduced a novel framework where the optical flow is computed as the solution of a minimization problem.
