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.
Slippy slidy particles
A friend of mine asked me a question about the way that standing waves make sand on a 2D plate make pretty patterns. So, I whipped up a quick 1D example in Mathematica. I threw 50 randomly distributed… Read More
Recurrence, heat maps, trajectories and fixations
More analysis from Dave Jacobs’ eye tracking project. We wrote all the analysis code ourselves in Mathematica. There’s a bug in the heat map compositing, but I shall procrastinate a solution soon. Lifted largely from Eye Tracking: A comprehensive… Read More
Recurrence plot
Eye tracking recurrence ala Anderson et al. 2013. With Dave Jacobs and the amazing Yarbus and Babcock software packages.
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
Anticipation of Sabre Fencing Attacks
A set of motion-capture trajectories for the Anticipation of Sabre Fencing Attacks paper by Pete Possidente and I. You can see the ‘whip’ of the tip of the sabre at the end of the attack (green dots on… Read More
