Why Does the Cortex Reorganize After Sensory Loss?

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 Continue reading

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 Continue reading

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 Continue reading

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 Continue reading

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 Continue reading

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 Continue reading

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 Continue reading

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 Continue reading
