My laboratory investigates human perception combining psychophysical experiments with computational modelling. Currently we have four research foci: First, to improve our image-based model of early spatial vision. Second, to connect early spatial vision with mid-level vision: perceived lightness, brightness and contrast in relation to surface reflectance and illumination in images of real scenes. Third, we investigate differences and similarities between deep convolutional neural networks and human object recognition. Fourth, we explore connections between causality from a perceptual as well as a machine learning perspective.

Accurate measurements need an accurate experimental setup and precise control devices as well as reliable software. My interest is precision psychophysics and so I administer our pool of fine instruments and servers, help improving our psychophysics lab, and then am able to perform exciting experiments.

Are human and machine vision relying on similar strategies for visual processing? I use psychophysical methods to better understand machine vision, and convolutional neural networks to model aspects of human visual processing. A current focus of my work is robustness: What can machine vision learn from the incredibly general robustness of the human visual system towards distortions of any kind?

I am interested in the perceptual representation of physical objects and scenes in the human visual system.
What are the perceptual properties that form the representation?
How does the visual system compute these properties?
In my current work, I investigate the perception of achromatic surface reflectance and illumination by combining psychophysical methods with images generated by modern computer-graphics algorithms.

How do humans and algorithms process causal information in vision? I develop new psychophysical methods to perform robust experiments, e.g. novel experiments to objectively quantify causal perception and apply the theory of causal inference to questions in cognitive science. My current focus is on the perception of the direction of causal flow. I study whether humans are able to perceive temporal causal relationships between objects.

There are always different scaling methods for sensory or psychological attributes. Lightness refers to the perception of a concrete property of an object, and for the scaling of lightness perception, will the results appear the same if different scaling methods are applied? I’m currently focusing on the analysis of psychophysical approaches for the human visual processing.
