An Improved LPTC Neural Model for Background Motion Direction Estimation

no code implementations22 Jan 2018 Hongxin Wang, Jigen Peng, Shigang Yue

A class of specialized neurons, called lobula plate tangential cells (LPTCs) has been shown to respond strongly to wide-field motion.

A Directionally Selective Small Target Motion Detecting Visual Neural Network in Cluttered Backgrounds

1 code implementation20 Jan 2018 Hongxin Wang, Jigen Peng, Shigang Yue

Discriminating targets moving against a cluttered background is a huge challenge, let alone detecting a target as small as one or a few pixels and tracking it in flight.
