Exploiting visual motion to understand our visual world
Motion is important for understanding our visual world. The human visual system relies heavily on motion perception to recognize the movement of objects, to infer the 3D geometry of a scene, and to perceive the emotions of other people. Modern computer vision systems also use motion signals …

Algorithms for estimating visual motion parameters from ganglion cell responses
This thesis is intended to present a specific sub-problem of a larger one we call the "Inverse Problem". We wish to estimate the velocity (speed and direction) of an edge of light which is moving on the photoreceptor layer of a rabbit retinal patch. We make these estimates based solely on the …

Common mechanisms for the representation of real, implied, and imagined visual motion
… Here we ask how a particular sensory property, visual motion, is represented when it is not directly perceived but only imagined or inferred from other cues. In a series of experiments, a motion adaptation paradigm is used to assess directional properties of the responses to mental imagery of …

Mechanisms of processing visual motion information: Psychophysical, bioelectrical and transcranial magnetic stimulation investigations
Liikumise tajumine on meie nägemissüsteemi üks olulisemaid funktsioone, võimaldades meil pidevalt muutuvad keskkonnas toime tulla ning ellu jääda. Oma funktsioonile vääriliselt keerukas on aga ka liikumisinformatsiooni töötlevate ja kasutavate mehhanismide töö ning tihtipeale mõjutavad nende tööd …

Effects of Age-Related Declines in Visual Motion Processing on Older Driver Safety
… investigating how age-related declines in visual motion processing affect older drivers’ ability to drive safely. In particular, these experiments assess the efficacy of: 1) A test of motion sensitivity, the Peripheral Motion Contrast Threshold (PMCT) test, which evaluates ones’ contrast …

On the role of correspondence noise in human visual motion perception. A systematic study on the role of correspondence noise affecting Dmax and Dmin, using random dot kinematograms: A psychophysical and modelling approach.
… false pairing of dots in adjacent frames) limits motion detection performance in random dot kinematograms (RDKs). The performance measures of interest are Dmax and Dmin i.e., the largest and smallest inter-frame dot displacement, respectively, for which motion can be reliably detected. Dmax and …

The development and plasticity of visuo-spatial orienting behaviors and underlying circuitry in adolescent mice
Sex differences in visual processing during behavior exist across a wide variety of species, from flies to humans. However, it remains unclear whether sexual dimorphism in natural visual behavior exists for standard laboratory strains of mice, a prominent model for understanding the neural basis of …

Functional analysis of middle temporal visual area and its associated behavior
… goal is to elucidate the circuitry of the visual cortex, to develop quantitative computational models of neuronal function in the visual cortex, and to establish how these models may relate to visual perception and visually guided behavior. Central to this goal is the analysis of functional …
