Abstract

We implement Adelson and Bergen's spatiotemporal energy model with extension to three-dimensional (x-y-t) in an interactive tool. It helps gain an easy understanding of early (first-order) visual motion perception. We demonstrate its usefulness in explaining an assortment of phenomena, including some that are typically not associated with the spatiotemporal energy model.

Keywords: eye movement; interactive; motion energy; science education; spatiotemporal filtering; visual illusions.

A laptop and a webcam explain motion visual illusions. Here, the illusory rotation of the rings in Pinna–Brelstaff illusion (Pinna & Brelstaff, 2000) is immediately revealed through the colors encoding motion energy (Adelson & Bergen, 1985). Refer to Figure 2 for more details.

The motion perception tool explains an assortment of visual illusions: stepping feet (Anstis, 2001; Bach, 2004; Kitaoka & Anstis, 2021), Kinegram (Bach, 2014), structure from motion (Bach, 2002; Rogers & Graham, 1979), Pinna–Brelstaff (Bach, 2003; Pinna & Brelstaff, 2000), Translational Moirè Patterns (Bach, 2013; Spillmann, 1993), Spine drift (Bach, 2011; Kitaoka, 2010), grid masking (Bach, 2019), and global motion influenced by arrows (@jagarikin, 2022).
