MHRC Member Dr Jessie LIN shares views on postpartum depression

Dr Jessie LIN, Member of the Mental Health Research Centre (MHRC) and Assistant Professor in the Department of Rehabilitation Sciences, shared her professional perspectives on postpartum depression in an interview with Bastille Post. Dr Lin explained that postpartum mothers can experience significant mood swings due to factors such as hormonal changes and challenges of maternal role adaptation. Family care and support can greatly help postpartum mothers to adapt to role changes and regulate emotions. She recommended seeking help from professionals as soon as possible should there be signs of postpartum depression or emotional distress.

RILS develops deep learning-based remote sensing image classification for land use land cover mapping in cloud-prone areas

Prof. WENG Qihao, Associate Director of the Research Institute for Land and Space (RILS) and his team have developed an integrated time series mapping method to enhance the land use and land cover (LULC) mapping accuracy and frequency in cloud-prone areas. Other key PolyU members on the research team include Prof. DING Xiaoli, Director of RILS, and Dr LI Zhiwei, Research Assistant Professor in the Department of Land Surveying and Geo-Informatics. The method incorporates spectral-indices-fused deep learning models and time series reconstruction techniques. The team applied the method to the cloud- and rain-prone Pearl River Delta (i.e., Guangdong–Hong Kong–Macao Greater Bay Area, GBA), and yielded an overall mapping accuracy of up to 87.01%, outperforming existing LULC products. This method has the potential to generate seamless and near real-time maps for different regions in the world by using deep learning models trained on datasets collected globally. It can provide high-quality LULC data sets at different time intervals for various land and water dynamics in cloud- and rain-prone regions.   Read the full paper: https://shorturl.at/jyj1B

PolyU develops and manufactures space instruments for the Nation’s Chang’e-6 mission, successfully completing the first lunar far side sampling in human history

In support of the Nation’s landmark sample return mission from the far side of the moon, the PolyU research team led by Prof. YUNG Kai-leung, Director of the Research Centre for Deep Space Explorations (RCDSE), Sir Sze-yuen Chung Professor in Precision Engineering, Chair Professor of Precision Engineering and Associate Head of the Department of Industrial and Systems Engineering, collaborated with the China Academy of Space Technology (CAST) to develop and manufacture the “Surface Sampling and Packing System” for this historic task. On June 3, the PolyU-developed system accomplished the tasks of automatic sample collection and packaging on the lunar surface, following the soft landing of the Chang’e-6 probe, marking a milestone in human space exploration. The probe has already taken off from the moon with the cargo of the first-ever lunar soil samples from the far side set to return to Earth on June 25. Unlike previous methods adopted by other countries involving drilling or manual excavation, PolyU’s “Surface Sampling and Packing System” is designed as fully automated multi-point lunar surface sampling and with a packaging mechanism. In Hong Kong, PolyU was involved in the design and manufacturing of Samplers A and B, together with two accompanying high temperature Near-field Cameras for multiple-point surface sample collections, and automatic vision guidance of the sampling, sample deposition and sample container pickup and precision placement into the ascender. The PolyU-designed and manufactured flight units also included a primary sealing and packaging system that consisted of a sample container and its sealing mechanism. The sampling process briefly started with the Near-field Cameras mounted on the robotic arm next to Samplers A and B. These Cameras guided the sampling and sample deposition into the PolyU sample container in the primary sealing and packaging system. Upon the completion of the sampling process, the sample container was sealed by the sealing and packaging device for picking up by the sampler which was vision-guided by the Near-field Cameras for automatic precision insertion into the ascender for transporting back to Earth.

Prof. WENG Qihao develops deep learning-based super-resolution method for building height estimation

A study by Prof. WENG Qihao, Associate Director of the Research Institute for Land and Space (RILS), Director of Research Centre for Artificial Intelligence in Geomatics, Member of the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI) and Chair Professor of Geomatics and Artificial Intelligence, and his research team, titled “A deep learning-based super-resolution method for building height estimation at 2.5 m spatial resolution in the Northern Hemisphere” was recently published in the journal Remote Sensing of Environment. Building height is an important indicator for assessing the level of urban development along the vertical dimension. Existing large-scale building height estimation studies focusing on coarse spatial resolution cannot reveal height variations across buildings in urban areas. The team proposed a deep learning-based super-resolution method to generate building height maps. The researchers created an open building height dataset with 45,000 samples covering 301 cities in the Northern Hemisphere, including China, the conterminous United States, and Europe. The dataset generated provides great potential in high-resolution database updating, urban planning, and natural disaster assessment, as well as a new perspective of how cutting-edge satellite imaging technology can be utilised in urban observation, measurement, monitoring, and management.
