Active Vision

This lecture summary was based on how we guide our own self-movement- what cues does one use to get to a target? The lecture explores two hypotheses: optic flow and egocentric direction. The lecture explores the role of extra retinal signals, models of heading, and fascinating phenomenons such as u...

A basic overview of some questions asked by my peers on the topics of vision during movement. A couple of past paper questions with some bullet point answers given by my lecturer.

My favourite yet one of the most complicated lectures of the series. This lecture explores Bayesian models of perception. It also explores the incredibly fascinating phenomenon of why Autistic people do not seem to experience visual illusions in the same way that neurotypical people do. Papers by Pe...

This lecture is aimed at understanding smooth eye pursuit movements and perceiving motion. looking at how we judge motion during pursuit using image-based compensation and extra retinal compensation. This lecture explores different types of illusions and how they effect our eyes to produce the illus...

This lecture focusses on explaining how we work out what is moving in our field of vision, e.g. how do we know it is a person moving in front of us as opposed to the tv behind them? It compares two theories: extra retina signals and visual masking. These can be complex theories to wrap your head a...

This lecture explains the different types of eye movements: conjugate, disconjugate, shifting, vestibule-ocular reflex, version & vergence, torsion, optokinetic nystagms, and smooth pursuit. The lecture focusses on how we use these eye movements when we are moving, and to perceive objects that are ...

This lecture is very interesting especially for a football fan! It explores why there is such a great difficulty in detecting whether a player is offside or not, due to an error in our vision (flag error or no flag error). It explores motion extrapolation, apparent ball size, and why goalkeepers s...
