My research investigates diverse aspects of processing in the human object recognition system. I am particularly interested in how we achieve visual and haptic object constancy and how we categorise stimuli in order to discriminate between different shapes. Haptics is active touch. I conduct empirical research which measures the speed and accuracy of human performance at recognising familiar and novel objects using our eyes or our hands in the face of disruptive object transformations such as plane and depth rotation and size changes. I also manipulate memory, context and attentional demands on participants. There are a group of us working on a range of topics within visual perception here at the School of Psychology in the University of Liverpool, in the Visual Perception Group. In particular, Marco Bertamini and I collaborate on research into people's perception and beliefs about images on mirrors and windows and we have also been investigating the role of convexities and concavities in determining the shape and, in particular, the part structure of objects.

The focus of this research is on how motor processes contribute to the perception of environment and of own body. Visual and body perception are usually considered to be determined by optical, ocular-motor and somatosensory information respectively. Some evidence, however, suggests that the way we act in a particular situation affects the way we perceive the environment and the body in this situation. We trace the origin of these motor effects under diverse context conditions. Kirsch, W.

Humans are routinely asked to evaluate the performance of other individuals, separating success from failure and affecting outcomes from science to education and sports. Yet, in many contexts, the metrics driving the human evaluation process remain unclear. Here we analyse a massive dataset capturing players' evaluations by human judges to explore human perception of performance in soccer, the world's most popular sport. View PDF on arXiv.

The study of time perception is a field within psychology , cognitive linguistics [1] and neuroscience that refers to the subjective experience, or sense, of time , which is measured by someone's own perception of the duration of the indefinite and unfolding of events. Though directly experiencing or understanding another person's perception of time is not possible, such a perception can be objectively studied and inferred through a number of scientific experiments. Some temporal illusions help to expose the underlying neural mechanisms of time perception. Pioneering work, emphasizing species-specific differences, was conducted by Karl Ernst von Baer.

Though numerous image quality measures have been proposed, the search for a reliable IQM is still vigorously pursued by different research groups around the world. There is a need to compare the already proposed IQMs with respect to their adherence to human image quality perception. A model that can accurately simulate the human perception of image quality is a challenging task due to limited human knowledge in the related domains of psychology, vision, biology etc. The psycho-visual experiments remain the most accurate way to model human perception of visual quality. In this paper, different state of the art full-reference objective image quality metrics IQMs are evaluated against human subjective judgments on standard LIVE image quality database. The difference mean opinion scores DMOS were calculated from human judgments on images distorted with white noise, Gaussian blur and Rayleigh fast-fading distortions. It is observed that though there is not a single winner, VIF and IFC seem to have a higher performance compared to other quality metrics.
