A biologically inspired approach to active visual target tracking is presented. The approach makes use of three strategies found in biological systems: space-variant sensing, a spatio-temporal frequency based model of motion detection and the alignment of sensory-motor maps. Space-variant imaging is used to create a 1-D array of elementary motion detectors(More)
BACKGROUND Oxidative Stress contributes to the pathogenesis of many diseases. The NRF2/KEAP1 axis is a key transcriptional regulator of the anti-oxidant response in cells. Nrf2 knockout mice have implicated this pathway in regulating inflammatory airway diseases such as asthma and COPD. To better understand the role the NRF2 pathway has on respiratory(More)
This paper presents a signal processing architecture for a sensory-motor system based on the smart sensor paradigm. The architecture is designed for an obstacle avoidance task by a mobile robot in an unstructured environment. Drawing inspiration from the field of behavior-based robotics, the development of the architecture is guided by an emphasis on the(More)
