I was trying to figure out why there were shading artifacts on a 3D object I created for some vision experiments. I’ve got a metric-ton of Mathematica I’ve written over the years for doing computational geometry and it stood… Read More
NewGlaven
Back in 1987 I wrote some code for generating ‘noisy objects’. I cleaned up that code over the years, enhanced some calculations, played with new Mathematica features. Now I’ve got stuff that looks like this. I’ll put a… 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
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
