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.

Research on traditional and deep learning strategies based on optical flow estimation - a review

Journal of King Saud University: Computer and Information Sciences
Optical flow estimation captures the motion information of objects in a scene through analyzing the displacement of pixels in an image over time. This technology provides a powerful tool for vision systems, allowing them to understand and perceive ...

Discrete Optimization for Optical Flow

, 2015
We propose to look at large-displacement optical flow from a discrete point of view. Motivated by the observation that sub-pixel accuracy is easily obtained given pixel-accurate optical flow, we conjecture that computing the integral part is the hardest piece of the problem.

Occlusion-Aware Unsupervised Learning of Monocular Depth, Optical Flow and Camera Pose with Geometric Constraints

Future Internet, 2018
We present an occlusion-aware unsupervised neural network for jointly learning three low-level vision tasks from monocular videos: depth, optical flow, and camera motion.

Propose of heel-strike and toe-off frame detection from gait video with optical flow and edge detection

Nihon Kikai Gakkai ronbunshu
We expect that gait will be useful information for detecting wandering and managing the health of elderly people utilizing a monitoring support robot. However, some kind of sensor is needed to extract pedestrian gait features.

An Optical Flow- and Machine Learning-Based Fall Recognition Model for Stair Accessing Service Robots

Mathematics
One of the reasons for the lack of commercial staircase service robots is the risk and severe impact of them falling down the stairs. Thus, the development of robust fall damage mitigation mechanisms is important for the commercial adoption of staircase ...
