The neuromorphic visual processing framework mimicking the biological vision system offers an alternative process into applying computer vision in everyday environment. With the growing interest for an effective approach for making detection of vulnerable road users for the purpose of safety enhancement, the proposed neuromorphic visual processing was tested on vulnerable road users such as cyclists...
With the ever expanding area of Underwater Sensor Networks (UWSN), many networking challenges have yet to be fully analyzed and addressed. Some of the specific challenges include limited energy resources, node mobility, and broadcast limitations. More importantly, in bigger UWSN with large amounts of sensed data, bottlenecks form at relay nodes transferring packets to the surface. Additionally, this...
There have been many researches on computer vision for the purpose of vehicle safety applications, making use of diverse methodologies like complex vision algorithms. However, despite its effectiveness, computer vision algorithms sometimes lack the robustness of mammalian visual system for the application in dynamic environments in vehicle driving conditions. We propose that the neuromorphic visual...
This paper describes the early vision of bio-inspired neuromorphic system enhanced by fuzzy processing, mimicking the primitive behaviour of visual cortex. The proposed bio-inspired system exhibits the biologically plausible function of mimicking the cat's visual cortex experimentation of Hubel and Wiesel. The neuromorphic implementation of vision is inspired by the directional visual signal selectivity...
A new spectrum sensing algorithm was proposed, which was based on spectrum covariance matrix. Theory analysis and simulation test showed that the method had improved the sensitivity and robustness of spectrum sensing.
Self-healing key distribution schemes enable a group user to recover session keys from two broadcast messages it received before and after those sessions, even if broadcast messages for middle sessions are lost due to network failure. These schemes are quite suitable for supporting secure communication over unreliable networks such as sensor networks and ad hoc networks. An efficient self-healing...
