Depth Image Processing for Obstacle Avoidance of an Autonomous VTOL UAV [PDF]
, 2006 We describe a new approach for stereo-based obstacle avoidance. This method analyzes the images of a stereo camera in realtime and searches for a safe target point that can be reached without collision.

Thinking Inside the Box: Considerations for Putting Data Physicalization Workshops in a Box
Computer Graphics Forum, EarlyView.Abstract Visualization researchers utilize workshops both for applied research and to engage different populations with visualization‐based activities. While there are many benefits to running visualization workshops, their utility and impact rely on the presence of a researcher who has deep knowledge about visualization theory and practice.

Stereo Vision for 3D Measurement in Robot Systems
Journal of Engineering and Sustainable Development, 2013 The major obstacle in the application of stereo vision to extract 3D information is the error in disparity map and highly computational cost at conventional computers.

Advances in 4D Representation: Geometry, Motion, and Interaction
Computer Graphics Forum, EarlyView.We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics

Design of a novel stereo vision navigation system for mobile robots [PDF]
, 2005 This paper presents a design method for a novel configured stereo vision navigation system for mobile robots, which is a catadioptric sensor called OSVOD (omnidirectional stereo vision optical device) based on a common perspective camera coupled with two

Cell Proliferation, EarlyView.Resveratrol‐loaded tetrahedral framework nucleic acids (tFNAs‐RSV) enable concurrent anti‐angiogenic and anti‐inflammatory therapy, enhancing ocular delivery and bioactivity. In hypoxia‐induced retinal neovascularisation, tFNAs‐RSV reduce neovascular lesions, vascular leakage and inflammatory infiltration by suppressing HIF‐1, p38 MAPK and NF‐κB p65 ...

Hybrid Collaborative Stereo Vision System for Mobile Robots Formation
International Journal of Advanced Robotic Systems, 2010 This paper presents the use of a hybrid collaborative stereo vision system (3D-distributed visual sensing using different kinds of vision cameras) for the autonomous navigation of a wheeled robot team.

Why Stereo Vision is Not Always About 3D Reconstruction [PDF]
, 1993 It is commonly assumed that the goal of stereovision is computing explicit 3D scene reconstructions. We show that very accurate camera calibration is needed to support this, and that such accurate calibration is difficult to achieve and maintain. We

Fish welfare in a changing world: New developments and current challenges
Journal of Fish Biology, EarlyView.Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...
