We WHITENING PLUS COOL MINT TOOTHPASTE investigated the effect of background scene on the human visual perception of depth orientation (i.e., azimuth angle) of three-dimensional common objects.Participants evaluated the depth orientation of objects.The objects were surrounded by scenes with an apparent axis of the global reference frame, such as a
Background: The population of older adults is growing in sub-Saharan Africa.Ageing exponentially increases fragility fracture risk.Of all global regions, Africa is projected to observe the greatest increase in fragility fractures.Fractures cause pain, disability and sometimes death, and management is expensive, often requiring complex healthcare de
Aiming at the problem of servoing task failure caused by the manipulated object deviating from the camera field-of-view (FOV) during the robot manipulator visual servoing (VS) process, a new VS method based on an improved tracking learning detection (TLD) algorithm is proposed in this article, which allows the manipulated object to deviate from the
