Real-time video image processing based on optical Kerr microcombs

<p>Advanced image processing will be crucial for emerging technologies such as autonomous driving, where the requirement to quickly recognize and classify objects under rapidly changing, poor visibility environments in real time will be needed. Photonic technologies will be key for next-generation signal and information processing, due to their wide bandwidths of 10’s of Terahertz and versatility. Here, we demonstrate broadband real time analog image and video processing with an ultrahigh bandwidth photonic processor that is highly versatile and reconfigurable. It is capable of massively parallel processing over 10,000 video signals simultaneously in real time, performing key functions needed for object recognition, such as edge enhancement and detection. Our system, based on a soliton crystal Kerr optical micro-comb with a 49GHz spacing with >90 wavelengths in the C-band, is highly versatile, performing different functions without changing the physical hardware.

Neural Networks Application on Human Skin Biophysical Impedance Characterizations

Artificial neural networks (ANNs) are basically the structures that perform input–output mapping. This mapping mimics the signal processing in biological neural networks. The basic element of biological neural network is a neuron. Neurons receive input signals from other neurons or the environment, process them, and generate their output which represents the input to another neuron of the network. Neurons can change their sensitivity to input signals. Each neuron has a simple rule to process an input signal. Biological neural networks have the property that signals are processed through many parallel connections (massively parallel processing). The activity of all neurons in these parallel connections is summed and represents the output of the whole network. The main feature of biological neural networks is that changes in the sensitivity of the neurons lead to changes in the operation of the entire network. This is called adaptation and is correlated with the learning process of living organisms. In this paper, a set of artificial neural networks are used for classifying the human skin biophysical impedance data.

Optimizing Radio Coverage Based on Cellular Automata

Autonomous surveillance systems based on wireless sensor networks have brought many benefits for understanding, protecting, and preserving biodiversity thanks to the latest sensor and telecommunication technologies. For example, in archipelagoes with many rocks of various shapes and elevations interleaved with water, it is hard to deploy wireless sensing systems for covering all these given areas. In these sensing systems, coverages are defined as where information is accessible. In this article, a new approach is proposed, adopting cellular automata and massively parallel processing on GPUs. This work relates to the development of parallel algorithms and CAD tools to optimize coverage oriented to efficient deployment of wide-range wireless networks for various purposes such as environmental surveillance, early warning systems for natural hazards and risks, taking into account turbulence in topology. Some experiments on radio coverage were done in different complex terrain areas given positive results in terms of performance and functional requirements.
