Our Elixir is a system that enhances video analytics performance from multiple IoT cameras by adjusting camera settings through Multi-Objective Reinforcement Learning (MORL). In tests, Elixir significantly outperformed default settings and time-sharing methods, improving detection rates for cars, faces, persons, and license plates, addressing challenges in multi-analytical unit settings.

APT: Adaptive Perceptual quality based camera Tuning using reinforcement learning
At the 9th International Conference on Internet of Things: Systems, Management and Security (IOTSMS 2022), we presented a novel reinforcement-learning system called APT, which dynamically adjusts camera parameters remotely via 5G networks. Experiments showed a significant accuracy improvement in video analytics, particularly a 42% enhancement in object detection, demonstrating APT's applicability across various tasks.
Enhancing Video Analytics Accuracy via Real-time Automated Camera Parameter Tuning
The paper presented at the 20th ACM Conference on Embedded Networked Sensor Systems (SenSys 2022) discusses a framework called CamTuner, which dynamically adjusts non-automated (NAUTO) camera parameters to enhance the accuracy of analytics units in video analytics pipelines (VAP). The researchers highlight that environmental changes can severely impact the accuracy of insights derived from surveillance cameras. By utilizing SARSA reinforcement learning and incorporating an analytics quality estimator alongside a virtual camera to expedite training, CamTuner improves detection accuracy significantly—detecting 15.9% more individuals and increasing vehicle recognition rates in diverse scenarios—thereby enabling advanced applications like automatic vehicle collision prediction.
Why is the video analytics accuracy fluctuating, and what can we do about it?
In ECCV 2022 Workshop on Adversarial Robustness in the Real World It is a common practice to think of a video as a sequence of images (frames), and re-use deep neural network models that are trained only on images for similar analytics tasks on videos. In this paper, we show that this “leap of faith” … Continue reading Why is the video analytics accuracy fluctuating, and what can we do about it?
DataXc: Flexible and efficient communication in microservices-based stream analytics pipelines
In the 20th IEEE International Conference on Pervasive Intelligence and Computing (PICom 2022) A big challenge in changing a monolithic application into a performant microservices-based application is the design of efficient mechanisms for microservices to communicate with each other. Prior proposals range from custom point-to-point communication among microservices using protocols like gRPC to service meshes … Continue reading DataXc: Flexible and efficient communication in microservices-based stream analytics pipelines
