    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

  • 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

  • Creating noisy stimuli

    So much noise. A method for creating a variety of pseudo-random `noisy’ stimuli that possess several useful statistical and phenomenal features for psychophysical experimentation is outlined. These stimuli are derived from a pseudo-periodic function known as multidimensional noise…. 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

  • Mathematica / Wolfram Language support for Microsoft VSCode

    I whipped up some simple syntax support for Mathematica / Wolfram Language in Microsoft’s VSCode. Grab it here: marketplace.visualstudio.com/items?itemName=flipphillips.wolfram-language.

  • Travels in the uncanny valley

    Here’s a screencast of my talk at the Rochester Institute of Technology Symposium on VR/AR Technology. It is from 3 December and a little low-key, so drink a little coffee before you start watching so you don’t fall… Read More

  • Enhancing research with Plenary Labs

    A new pub with some good friends on the impending doom of science funding and what to do about it. Authored well before the new administration was a gleam in our collective eyes.   Citation: Pawan Sinha, Peter… Read More

  • Fuzzy Logic package for Mathematica

    I was working on a project in Gießen last week and needed some code I wrote back in the late 1980’s / early 1990’s. Sadly, this is no replacement for the super cool FuzzyLogic Mathematica package (RIP). It… Read More

    Veiled Virgin Stuff for VSS 2017  

  • Glaven 13

    Glaven Object Files

    I’ve posted the Glaven STL and OBJ object files in the Software, Data & Geometry section. Go have a look and let me know if you use them or even download them for that matter.

  • Gibson ‘Feelie’ Object Files

    I’ve created a OBJ and STL repository of printable / renderable versions of Gibson’s ‘feelies’ haptic dataset. Go have a look and let me know if you download and/or use them.

  • Temporal Integration at Extremely Low Contrast

    Gabe Diaz’ thesis from 2004.   The goal of this research is to investigate the relationship between the abil- ity to recognize objects at very low contrasts and the duration for which they are presented. Empirical evidence suggests… Read More
