Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investiga ....Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investigate complex motion processing in the primate brain by recording the responses of neurons in identified regions of the visual cortex of macaque monkeys to a range of behaviourally relevant motion stimuli.Read moreRead less
Stereoscopic Vision at Large Distances. This project measures the benefits of stereopsis, which is a perception of depth obtained from binocular vision, at distances of tens to hundreds of meters. Almost nothing is known of our stereoscopic abilities over this range and thus this is new and fundamental data about human vision. We will investigate how monocular and binocular information is combined at large distances; an issue relevant to sensor fusion, a central problem in neuroscience. The rese ....Stereoscopic Vision at Large Distances. This project measures the benefits of stereopsis, which is a perception of depth obtained from binocular vision, at distances of tens to hundreds of meters. Almost nothing is known of our stereoscopic abilities over this range and thus this is new and fundamental data about human vision. We will investigate how monocular and binocular information is combined at large distances; an issue relevant to sensor fusion, a central problem in neuroscience. The research is also critical for any tasks involving judgments over long distances including the recognition of distant targets and their relationships as well as the visual guidance of vehicles such as helicopters. It will also provide critical information to designers of binocular instruments.Read moreRead less
How, What and Who in Human Communication: Movement of Face and Voice. The aim of this project is to identify the essential characteristics of tone, affect, and identity from face and voice using a combination of signal processing, biological, and behavioural techniques in order to develop a comprehensive model of auditory-visual speech processing and communication. This research will significantly improve understanding of the basis of auditory-visual perception and production in tonal languages ....How, What and Who in Human Communication: Movement of Face and Voice. The aim of this project is to identify the essential characteristics of tone, affect, and identity from face and voice using a combination of signal processing, biological, and behavioural techniques in order to develop a comprehensive model of auditory-visual speech processing and communication. This research will significantly improve understanding of the basis of auditory-visual perception and production in tonal languages and in affective communication, facilitate links between neurophysiological processes and auditory-visual speech processing; and contribute to applications in automatic person recognition, automatic speech recognition, text-to-speech systems, and talking head aids for the hearing impaired.Read moreRead less
Solving the passport problem: re-designing photo-ID to improve recognition. We aim to contribute to national security and crime prevention by increasing the accuracy with which security staff can check the validity of photo-ID documents such as passports. Research shows that it is surprisingly difficult to determine if the image on a photo-ID document is of the bearer, and as a result it is likely that fraudulent use of photo-ID documents sometimes goes undetected. Our novel approach is to use ....Solving the passport problem: re-designing photo-ID to improve recognition. We aim to contribute to national security and crime prevention by increasing the accuracy with which security staff can check the validity of photo-ID documents such as passports. Research shows that it is surprisingly difficult to determine if the image on a photo-ID document is of the bearer, and as a result it is likely that fraudulent use of photo-ID documents sometimes goes undetected. Our novel approach is to use our knowledge of unfamiliar face perception to develop new image formats for photo-ID documents which increase the accuracy with which security staff can detect identity fraud.Read moreRead less
