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
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
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
Spring 2018 Vision in Animals, Humans and Machines — Final Projects
Vision in Humans, Animals and Machines is a seminar / hands-on course where we engage in a sort of comparative neuroscience with respect to how organic and inorganic systems ‘see’. Some things are hard for animals, some things… 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
Perceptual representation of visible surfaces
What is a surface, anyway? Two experiments are reported in which we examined the ability of observers to identify landmarks on surfaces from different vantage points. In Experiment 1, observers were asked to mark the local maxima and… Read More
Vision Science 2014 poster
Here’s Phillips, Mazzarella & Docter (2014) for VSS. Get the PDF here Phillips2014 (Draft of 13 May). Specularity and shape from line drawings. If you’re in Florida next week drop in and say ‘hi’. Or not. An interesting thought: this could… Read More
Pete Experiment
Going to have to hurry up to get my stuff ready for VSS. So much data, so little time. A project I’m working on with Julia Mazzeralla and my ol’ pal Pete Docter.
Marroquin patterns
I notice that I seem to generate a lot of images while doing analysis, largely using Wolfram Research’s Mathematica… so, maybe every day I should post one of those images here- an image of something I’m working on,… Read More
