Cuttlefish vision in a 3-D world

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

BVI Seminar with speaker Professor Daniel Osorio from University of Sussex.

VILSS: Human Action Recognition and Detection from Noisy 3D Skeleton Data

Mohamed Hussein, Egypt-Japan University of Science and Technology Human action recognition and human action detection are two closely related problems. In human action recogniton, the purpose is to determine the class of an action performed by a human subject from spatio-temporal measurements of the subject, which are cropped in the time dimension to include only the […]

BVI Seminar: The effectiveness of camouflage; predator learning and new modelling approaches

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

Jolyon Troscianko, Exeter University Abstract: Evading detection is crucial for the survival of many animals, and number of different means of achieving camouflage have been discovered. I will discuss my recent work investigating whether some types of camouflage are more easily learnt than others. If predators learn to find one type of prey more efficiently […]

BVI Seminar: Marked Point Processes for Object Detection and Tracking in High Resolution Images: Applications to Remote Sensing and Biology

Josiane Zerubia, INRIA, France Abstract: In this talk, we combine the methods from probability theory and stochastic geometry to put forward new solutions to the multiple object detection and tracking problem in high resolution remotely sensed image sequences. First, we present a spatial marked point process model to detect a pre-defined class of objects based on […]

BVI SEMINAR:New technologies for improving the representation of human vision

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

Robert Pepperell, Cardiff Metropolitan University Abstract: What is the best way to represent the three-dimensional world we see on a two-dimensional surface? For several hundred years there was basically one answer to this question: use linear perspective. Linear perspective is a method of mapping rays of light onto an image plane in a way that […]

BVI Seminar: Exogenous visual attention and the primary visual cortex

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

Zhaoping Li, University College London I will present a theory that primary visual cortex creates a saliency map to guide attention exogenously, and show how this explains and predicts experimental data in physiology and in visual behavior. Implications of this theory will be discussed. Biography: I obtained my B.S. in Physics in 1984 from Fudan […]

BVI Seminar: Psychophysical probes into spatial vision: you ain’t seen nothin’ yet.

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

Tim Meese, School of Life and Health Sciences, Aston University. Everyone knows what cosmologists do: they gaze out into the sky to see the secrets of what’s out there, matching observations with theory to understand how the universe came about. Visual psychophysicists are motivated by a similar sense of wonder; but the universe they want to […]

BVI Seminar: Visual concealment as foreign policy: camouflage as signaling friends and foes.

Seminar Room, Life Sciences Building Tyndall Avenue, Bristol

 László Tálas, Camo Lab, University of Bristol Abstract: Why do armies operating in the same environment (e.g. temperate woodland) wear markedly different dress? The primary function of military camouflage is generally understood to be concealment, however the vast diversity of camouflage patterns (over 600 patterns in the past century) suggests additional design factors. One hypothesis is […]
