Why Does the Cortex Reorganize After Sensory Loss?

meh

Investigating the Teleology of Cortical Reorganization A growing body of evidence demonstrates that the brain can reorganize dra- matically following sensory loss. Although the existence of such neuroplastic crossmodal changes is not in doubt, the functional significance of… Read More

Retina and LGN

A demonstration written in Mathematica to show the interaction of the retina and LGN on the sampling of image information from the eyes. You can play with the receptive field size to see how the whole “Hybrid Images”… Read More

VSS 2018 – Shape scission: causal segmentation of shape

Warts, cracks, causal shape segmentation. Research on shape perception usually focuses on the estimation of local surface geometry through cues like stereopsis, shading, or texture. Here, we argue that observers use these shape estimates to infer other object… Read More

VSS 2018 – Gravity and Ground Plane Geometry in Perspective Images

“The small things float to the top of… gravity” — Rickie Lee Jones Renaissance artists noticed that placing objects on a visible ground plane anchors them stably, making it easy to perceive their depth. Subsequently, they developed methods… Read More

VSS 2018 – Exploring the Uncanny Valley

Balls! Bouncing balls. This is science so we gotta start somewhere. Mori’s Uncanny Valley phenomena isn’t limited to robotics. It has been observed in many other areas, including the fine arts, especially photorealistic painting, sculpture, computer graphics, and… Read More

Fechner’s Aesthetics Revisited

Isn’t it beautiful? Gustav Fechner is widely respected as a founding father of experimental psychology and psychophysics but fewer know of his interests and work in empirical aesthetics. In the later 1800s, toward the end of his career,… Read More

Combinational Imaging: Magnetic Resonance Imaging and EEG Displayed Simultaneously

Before fMRI (Functional Magnetic Resonance Imaging) existed, I got to do this. We were one of the first labs to do this pre ‘functional’ functional imaging. Instead of volume rendering (which I would move on to Pixar to… Read More

The perception of surface orientation from multiple sources of optical information

The first piece of work in did in the “Todd Lab” at OSU. I had just come off five years at Pixar and a year back in grad school in the Architecture and Planning department. I wrote most of… Read More

Perceiving Object Shape from Specular Highlight Deformation, Boundary Contour Deformation, and Active Haptic Manipulation

Haptic and visual ‘contours’ It is well known that motion facilitates the visual perception of solid object shape, particularly when surface texture or other identifiable features (e.g., corners) are present. Conventional models of structure-from-motion require the presence of… Read More

Haptic shape discrimination and interhemispheric communication

Touching. In three experiments participants haptically discriminated object shape using unimanual (single hand explored two objects) and bimanual exploration (both hands were used, but each hand, left or right, explored a separate object). Such haptic exploration (one versus… Read More
