A Vision-Based Closed-Form Solution for Measuring the Rotation Rate of an Object by Tracking One Point
Daniel Raviv, Juan D. Yepes, Eiki M. Martinson
We demonstrate that, under orthographic projection and with a camera fixated on a point located on a rigid body, the rotation of that body can be analytically obtained by tracking…

Visual Looming from Motion Field and Surface Normals
Juan Yepes, Daniel Raviv
Looming, traditionally defined as the relative expansion of objects in the observer's retina, is a fundamental visual cue for perception of threat and can be used to accomplish col…
