The Sixth Visual Object Tracking VOT2018 Challenge Results
The Visual Object Tracking challenge VOT2018 is the sixth annual tracker benchmarking activity organized by the VOT initiative. Results of over eighty trackers are presented; many are…

The results show that view-based homing with panoramic images is in principle feasible in natural environments and does not require the identification of individual landmarks.

It is shown that, during landing, the bee decelerates continuously and in such a way as to keep the projected time to touchdown constant as the surface is approached, which reflects a surprisingly simple and effective strategy for achieving a smooth landing.
Reflective surfaces for panoramic imaging.
A family of reflective surfaces is presented that, when imaged by a camera, can capture a global view of the visual environment that is not affected by the distortions and aberrations found in refractive wide-angle imaging devices.
Robot navigation inspired by principles of insect vision
Vision‐based terrain following for an unmanned rotorcraft
The optic flow image interpolation algorithm (I2A) is extended to include an adaptive capability providing a greater dynamic range, which exhibits excellent robustness in an outdoor environment and makes it suitable for flight control in a real‐world environment.
Biomimetic Visual Sensing and Flight Control
Several research efforts aimed at developing new sensing and control algorithms inspired by insect vision and flight behaviors are discussed, which suggest that simple reflexive schemes combined with the measurement of optic flow may be sufficient to provide many aspects of autonomous navigation in complex environments.
Insect behaviour: Motion camouflage in dragonflies
Stereo cameras are used to reconstruct the movements in three dimensions of dragonflies, and show that these insects actively use motion camouflage to disguise themselves as stationary during territorial aerial manoeuvres.
Landing Strategies in Honeybees and Applications to Uninhabited Airborne Vehicles
An application of insect visuomotor behavior to automatic control of landing is explored and the current efforts at exploring the applicability of this and related techniques to the guidance of uninhabited airborne vehicles (UAVs) are outlined.
