Optic-flow is believed to be the main source of information allowing insects to control their flight. Some researchers have tried to apply this paradigm to small unmanned aerial vehicles (UAVs). So far, none of them has been able to demonstrate a fully aut ...
The perception of a visual target can be strongly influenced by flanking stimuli. In static displays, performance on the target improves when the distance to the flanking elements increases-presumably because feature pooling and integration vanishes with d ...
The perception of a visual stimulus is strongly modulated by surrounding elements. This phenomenon, called contextual modulation, can be exemplary observed in a large number of visual illusions, e.g. in the tilt-illusion where a vertical grating appears ti ...
Surrounding environment is mainly perceived through sight and hearing. Our sense of touch is mostly dedicated to explore the surface of objects using hands and fingers. Tactile sensitivity of the body skin is rather limited in common life, however this rep ...
Human visual perception is a fundamentally relational process: Lightness perception depends on luminance ratios, and depth perception depends on occlusion (difference of depth) cues. Neurons in low-level visual cortex are sensitive to the difference (but n ...
Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resour ...
Simultaneous and temporal masking are two frequently used techniques in psychology and vision science. Although there are many studies and theories related to each masking technique, there are no systematic investigations of their mutual relationship, even ...
We propose a new content-aware image resizing scheme, "Stream Carving", which is based on the well-known seam carving method. Our algorithm may introduce larger seams in the retargeted image, i.e. seams with a width larger than one pixel, that we call "str ...

People tend to grossly overestimate the size of their mirror-reflected face. Although this overestimation bias is robust, not much is known about its relationships to self-face perception. In two experiments, we investigated the overestimation bias as a fu ...
Geometry is closely linked to visual perception; yet, very little is known about the geometry of visual processing beyond early retinotopic organization. We present a variety of perceptual phenomena showing that a retinotopic representation is neither suff ...
