Splitting Tracking through Crossing Fibers: Multidirectional Q-Ball Tracking
We present a new tracking algorithm based on the full multidirectional information of the diffusion orientation distribution function (ODF) estimated from Q-Ball Imaging (QBI). Fr...

Active Visual Tracking of Heading Direction By Combining Motion Energy Neurons
- We describe a robotic vision system that aligns a camera's optical axis with its direction of translation by estimating the focus of expansion. Visual processing is based on...
