Merging the senses into a robust percept
To perceive the external environment our brain uses multiple sources of sensory information derived from several different modalities, including vision, touch and audition. All these differentExpand

Grasping Visual Illusions: No Evidence for a Dissociation Between Perception and Action
Neuropsychological studies prompted the theory that the primate visual system might be organized into two parallel pathways, one for conscious perception and one for guiding action. SupportingExpand

Where did I take that snapshot? Scene-based homing by image matching
TLDR
We show that most existing approaches to scene-based homing implicitly assume an isotropic landmark distribution. Expand

Separate neural pathways for the visual analysis of object shape in perception and prehension
BACKGROUND Earlier work with neurological patients has shown that the visual perception of object size and orientation depends on visual pathways in the cerebral cortex that are separate from thoseExpand

Do HDR displays support LDR content?: a psychophysical evaluation
TLDR
The development of high dynamic range (HDR) imagery has brought us to the verge of arguably the largest change in image display technologies since the transition from black-and-white to color television. Expand

Going into depth: Evaluating 2D and 3D cues for object classification on a new, large-scale object dataset
TLDR
We introduce a novel, large dataset containing 18 categories of objects found in typical household and office environments—we envision this dataset to be useful in many applications ranging from robotics to computer vision. Expand

Orientation dependence in the recognition of familiar and novel views of three-dimensional objects
We report four experiments that investigated the representation of novel three-dimensional (3D) objects by the human visual system. In the first experiment, canonical views were demonstrated forExpand

Face recognition under varying poses: The role of texture and shape
Although remarkably robust, face recognition is not perfectly invariant to pose and viewpoint changes. It has long been known that both profile and full-face views result in poorer recognitionExpand

Bayesian integration of visual and vestibular signals for heading.
TLDR
We found that even when there was a relatively large conflict between the visual and vestibular cues, participants exhibited a statistically optimal reduction in variance. Expand

Inverse perspective mapping simplifies optical flow computation and obstacle detection
We present a scheme for obstacle detection from optical flow which is based on strategies of biological information processing. Optical flow is established by a local “voting” (non-maximumExpand
