Facial Image Analysis
The “AI and Robotics” group has been engaging in facial image analysis with research on face detection and recognition, facial image super-resolution and enhancement, facial expression recognition, etc. This comprehensive research on facial image analysis supports a wide range of applications, including security and access control, human-computer interactions, augmented reality, virtual reality, education, entertainment, etc.
Spoken Language and Audio Signal Processing
The “AI and Robotics” group has been engaging in spoken-language and audio signal processing research with applications to voice biometrics, next-generation human-computer interaction, and healthcare. We have developed far-field speaker verification systems and multi-lingual speaker diarization systems for Huawei Technologies Corporation and collaborated with Tencent AI Lab to advance deep speaker-embedding algorithms.
Indoor Positioning and Wireless Sensing in IoT
The “Future Wireless Networks and IoT" Research Group has been engaging in indoor positioning and wireless sensing research. We have deployed a number of indoor positioning systems (IPS) based on Bluetooth low energy (BLE) beacons and developed mobile apps to implement our cooperative positioning algorithms for indoor navigation and tracking in exhibition environments.
Smart Indoor IoT-assisted Cultivation System
Through innovative research and development of effective photosynthetic-active-radiation lighting system, hydroponic and aeroponic irrigation systems, network sensing and novel environmental control, optimized growth profiles and renewable energy system, we explored and developed high performance IoT-assisted plant cultivation systems that can be integrated into urban buildings for sustainable and stable food supply.
Optical Transmission Techniques for High Capacity Optical Networks
In the past few years, the “Photonic Systems and Devices” Research Group at PolyU have worked closely with Huawei Technologies Co. Ltd., the global leader in information and telecommunication solutions, to develop optical communication technologies that enable the realization of multi-terabit optical networks. In particular, we have developed transmission and detection techniques as well as related digital signal processing (DSP) algorithm that allow the realization of 400Gbit/s per wavelength transmission (total capacity of a few tens of Terabit per fiber) over a few thousand kilometers.
