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…
Research Experience of an Undergraduate Student in Computer Vision and Robotics
Ayush V. Gowda, Juan D. Yepes, Daniel Raviv
This paper focuses on the educational journey of a computer engineering undergraduate student venturing into the domain of computer vision and robotics. It explores how optical flo…
Invariant-based Mapping of Space During General Motion of an Observer
Juan D. Yepes, Daniel Raviv
This paper explores visual motion-based invariants, resulting in a new instantaneous domain where: a) the stationary environment is perceived as unchanged, even as the 2D images un…
Time-based Mapping of Space Using Visual Motion Invariants
Juan D. Yepes, Daniel Raviv
This paper focuses on visual motion-based invariants that result in a representation of 3D points in which the stationary environment remains invariant, ensuring shape constancy. T…
Detecting Moving Objects Using a Novel Optical-Flow-Based Range-Independent Invariant
Daniel Raviv, Juan D. Yepes, Ayush Gowda
This paper focuses on a novel approach for detecting moving objects during camera motion. We present an optical-flow-based transformation that yields a consistent 2D invariant imag…
