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

VSS Analysis Continues

It never ends. Depth maps.            

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.          

Curvature Field Computations

Curvature field calculations for a random noisy shape. Colors represent magnitude of curvature. Iso-contours also shown in lovely pink.          

Hairy Glaven

Hairy elongated noisy stimulus.   The lines are surface normals, sampled across the object. They are generated using a continuous random method (sometimes called ‘noise’) and were used to test symmetry perception in 3D shape.      … Read More

Sculpted Golden Boy

A stimulus, # 13, otherwise known as ‘golden boy’ Colors indicate mapping of under- and over-sculpt from a shape production experiment where we had artists and non-artists reproduce shapes using only vision, touch, or some combination of both… Read More

Statistical Shape of 3D Objects.

Statistical distribution of shape on a 3D object.   A bell pepper from Norman et al. Each color represents a class of shape ala Koenderink’s “Shape Index”. The histogram below shows the distribution along with a key to the… Read More
