Neuromorphic computing has been identified as an ideal candidate to exploit the potential of event-based cameras, a promising sensor for embedded computer vision. However, state-of-the-art neuromorphic models try to maximize the model performance on large platforms rather than a trade-off between memory requirements and performance. We present the first deployment of an embedded neuromorphic algorithm on Kraken, a low-power RISC-V-based SoC prototype including a neuromorphic spiking neural network (SNN) accelerator. In addition, the model employed in this paper was designed to achieve visual attention detection on event data while minimizing the neuronal populations’ size and the inference latency. Experimental results show that it is possible to achieve saliency detection in event data with a delay of 32ms, maintains classification accuracy of 84.51% and consumes only 3.85mJ per second of processed input data, achieving all of this while processing input data 10 times faster than real-time. this trade-off between decision latency, power consumption, accuracy, and run time significantly outperforms those achieved by previous implementations on CPU and neuromorphic hardware.

Multi-user volumetric content delivery can enable numerous appealing applications, such as online education, telehealth, multiuser AR/VR training, immersive collaborative analytics, etc. However, the bandwidth-intensive nature of volumetric video streaming makes existing systems for single-user experiences hard to scale to multi-user scenarios. To address this critical issue, in this paper, we first perform a scaling experiment on mmWave networks that offer the needed multi-Gbps throughput and identify two key challenges of streaming high-quality volumetric videos to multiple users: frequent blockages of mmWave links and high transmission redundancy among users. To solve these problems, we propose a first-of-its-kind, agile, and cross-layer system, dubbed M5, for improving the performance and quality of experience for multi-user volumetric video streaming. M5 utilizes the 6DoF motion prediction of users to proactively adapt mmWave beams and prefetch frames to mitigate the blockage effects. Furthermore, it takes advantage of the multicast transmission to deliver the overlapped common content within users' viewports to reduce the bandwidth requirement. Our extensive experiments on a real testbed and with a trace-driven simulator show that M5 can effectively improve the frame rate by 44.1% and volumetric video quality by 62.3% compared to the state-of-the-art system.

A complete sensor network should include sensors, data processing, and data services. However, to establish the legitimacy of sensor data for urban governance, sensor networks should go beyond simple deployment of sensors in the built environment and strive for deeper integration of data services within civil society. this paper presents the Taiwan AirBox Project as an exemplary case of practical deployment of a sensor network to discuss the topics of open data, value-added services, and joint calibration services; as well as how these services generate productive public-private *** AirBox project adopted a strategy of combining open-source hardware, flexible database API, multiple value-added data services, and open-joint calibration to gradually enhance the data quality. the results suggested that: 1. open hardware and open source software are keys to expanding the deployment of the sensor network; 2. open data and diverse value-added services enhance the public's environmental awareness and advocacy; 3. the open joint-calibration system helps connect government policy formulation with public environmental *** addition, the AirBox project demonstrates the feasibility of a democratized deployment strategy. "Openness" serves as the foundation for mutual trust, communication, cooperation, and co-creation among stakeholders involved in the deployment process.
