PolyU partner with Transsion to advance display colour management technology

The Hong Kong Polytechnic University (PolyU) collaborates with Transsion Holdings to translate the latest research results of colour characterisation into actual products, so as to improve the display quality and user experience of smartphones. As smart products become indispensable in our daily life, the improvement of user experience on imaging systems largely depends on the colour calibration and management technologies. The research team led by Prof. WEI Minchen, Tommy, Director of Colour Imaging and Metaverse Research Centre at PolyU proposes to apply a 3D piecewise model to tackle the poor performance of conventional models. Based on the measurements of the tristimulus values of 64 combinations of digital signal values, the 3D piecewise model divides the display gamma encoded colour space into 27 subspaces and characterizes the crosstalk effects. This high-quality solution allows a fast and automatic colour calibration of smartphone displays, resulting in an average color difference ΔE00 reduced from 3.96 to 0.72, which reaches the industry-leading level. This solution has been implemented on the smartphone production line for automatic colour calibration, ensuring that users can enjoy accurate and faithful colour appearance under a wide range of viewing conditions.

The research focuses on achieving decarbonisation through clean electricity with special emphasis on the production of valuable chemicals from the earth’s abundant resources.  Engineering plays a crucial role in promoting sustainable development by creating solutions for energy systems, production, and resource management that can reduce carbon emissions, conserve resources and protect the environment. The primary focus of Dr ZHANG’s highly cited papers is the exploration of novel layered materials for clean energy conversion. His research interests also extend to the conversion of waste pollutants such as carbon dioxide, nitrate and biomass into valuable chemical and fuels.  Dr ZHANG said, “I am thrilled by this prominent achievement to influence frontier sciences and subsequent innovative applications. Our research has enhanced scientific knowledge in materials science and chemical engineering, particularly in the understanding of 2D materials and development of electrochemical reactors for sustainable production.” Advancing the knowledge of material structures and catalytic processes is crucial to clean energy production. Dr ZHANG said, “Our research has facilitated the development of practical reactors capable of producing valuable chemicals at an industrial-relevant rate. These novel findings have significant impact on the development of sustainable manufacturing, environmental remediation and resources efficiency.”    Novelty in research Researchers work tirelessly to bring scientific breakthroughs. Dr ZHANG’s works have unravelled fundamental theories and technologies in materials sciences which serve as useful references for other researchers to explore further across various disciplines.  Dr ZHANG said, “I’m encouraged by our highly cited works, which eventually bridge the gaps between frontier scientific findings and practical production applications.” For instance, one of his highly cited research on catalytic interface engineering and electrochemical reactor has facilitated the design for hydrogen peroxide (H2O2) production.  The study “Electrochemical oxygen reduction to hydrogen peroxide at practical rates in strong acidic media” was published in Nature Communications in 2022. The research presented a cation-regulated interfacial engineering approach to promoting the H2O2 selectively under industrial-relevant generation rates in strongly acidic media. A double-PEM (proton exchange membrane) solid electrolyte reactor was further developed to realise a continuous, selective and stable generation of H2O2.  Practically, the acidic H2O2 solution delivers a wider range of applications and greater demand. This strongly motivates studies in the high-performance electrochemical generation of H2O2 in acidic media. Another novel study in material sciences demonstrated a unique approach to structure tuning of material, resulting in effective manipulation of its catalytic properties and functionalities. The research meticulously investigated structural change during the lithiation-induced amorphization process. The highly cited research, “Lithiation-induced amorphization of Pd3P2S8 for highly efficient hydrogen evolution” was published in Nature Catalysis in 2018.  The study showcased a breakthrough in the amorphization of layered materials, transforming inherently non-catalytic materials into highly efficient catalysts for cathodic hydrogen production. The atomic-level structural engineering of inorganic materials has proven to be a compelling strategy for tuning their physical, chemical and electronic properties, thus enhancing their performance in various applications, particularly in electrocatalysis.  Increasingly concerns about the rising levels of carbon dioxide (CO2) and its influence on climate change have made it essential to create efficient strategies to reduce CO2 emissions. Dr ZHANG's team identifies the potential of integrating CO2 capture and electrochemical conversion as a promising approach to tackle this challenge. Recently, Dr ZHANG and his research team have made a noteworthy advancement in the sustainable energy field through their groundbreaking study published in  . The review paper "Integration of CO2 capture and electrochemical conversion" delves into the exploration of combining CO2 capture and electrochemical conversion. A comprehensive investigation was conducted in the study to develop an efficient and sustainable system that captures CO2 from emission sources, and subsequently converts it into valuable chemicals or fuel. The findings provide valuable insights and practical strategies for researchers, policymakers, and industries working towards sustainable CO2 management and developing a circular carbon economy. The integration of CO2 capture and electrochemical conversion can help us move toward a greener and more sustainable future.   Go beyond Constraint The transition from the ubiquitous goal of sustainability and clean energy to intricate scientific concepts and discoveries poses the challenge of consistently pushing the boundary of knowledge while upholding high research standards and adapting to evolving technological landscape. Throughout the research journey, Dr ZHANG’s studies have fostered interdisciplinary collaborations in pursuit of sustainable developments across various fields.   “Knowing that your work has significantly impacted the field, leading to further discoveries and innovations, is immensely rewarding. While keeping up with the latest advancements and addressing new research questions can be demanding, it is also highly fulfilling,” said Dr ZHANG.  The high citation rates would increase the researcher’s visibility within the scientific community and attract more opportunities for collaboration, driving the vision to shape the future of sustainable research on a global scale.  Looking forward, Dr ZHANG said, “I am actively seeking collaborative opportunities while staying focused on my research vision. My goal is to drive positive change and advance the field of clean energy conversion.”  Research Interests: Electrocatalysis, Carbon Capture and Conversion, Electrochemical Reactor Design; Membrane Electrode Assembly, 2D Nanomaterials Highly Cited Researcher: 2020-2022 (Clarivate Analytics) Selected Highly Cited Publications: X.

A vision to enhance image quality and analysis

Being open and embracing new techniques are crucial to scientific research.  The high-quality images and videos on our smartphones and digital devices nowadays are the product of scientists’ scrupulous research on innovative solutions. Prof. Lei ZHANG, Chair Professor of Computer Vision and Image at The Hong Kong Polytechnic University (PolyU), has contributed to this field of study with a vision of enhancing image resolution and quality for our daily life applications.  Better picture quality is an end result of image enhancement and analysis, which are increasingly helpful for diverse digital and computer products. Prof. ZHANG’s research has substantially influenced the field of image restoration, enhancement and quality assessment.  Image restoration and enhancement aim to reproduce a high-quality image from a low-quality input that is noisy, blurred or low-resolution, while quality assessment seeks to predict the perceptual quality of a given image. Prof. ZHANG’s works in these areas are frequently cited by academics and industry professionals for useful and novel ideas and references.    Highly cited research on image enhancement With research interests focused in computer vision and image processing, Prof. ZHANG’s studies have profoundly benefited ubiquitous applications on smartphone and digital cameras. Over the decade, research outputs have contributed to enhancing the quality of photographs on cameras, image editing software and biomedical image analysis.  Prof. ZHANG said, “Being open and embracing new techniques are important to scientific research. The honour to be a highly cited researcher has driven me to a more valuable contribution in this field, with impactful research to generate sustainable influence and value to the society.”    Enhancing images Prof. ZHANG’s research “Weighted Nuclear Norm Minimization with Application to Image Denoising” showed that the weighted nuclear norm minimization (WNNM) algorithm outperforms many previous state-of-the-art denoising algorithms such as block-matching and 3D filtering (BM3D) for noise reduction in terms of both quantitative measure and visual perception quality. WNNM has become one of the most representative denoising algorithms before the deep learning era.   One of Prof. ZHANG’s highly cited papers, titled "Beyond a Gaussian Denoiser: Residual Learning of Deep CNN for Image Denoising" on IEEE Transactions on Image Processing, presented one of the first denoising convolutional neural network (DnCNN) models. This research finding not only produces favourable image-denoising performance quantitatively and qualitatively but also delivers promising run time by GPU implementation. Significantly, it paves the way to investigate proper CNN models for denoising images with complex noise and image restoration tasks.  With the rapid proliferation of digital imaging and communication technologies, image quality assessment (IQA) is crucial for numerous applications such as image acquisition, transmission, compression, restoration and enhancement. A novel feature similarity (FSIM) index for full reference IQA was introduced in the paper named “FSIM: A Feature Similarity Index for Image Quality Assessment.” It is proven that FSIM can achieve much higher consistency with subjective evaluations than state-of-the-art IQA metrics.    Open to change Technology, particularly in the field of computer science, moves incredibly fast. However, research does not necessarily move at the same speed. In the past 20 years, the dominant technologies in image processing, computer vision and pattern recognition, which are of Prof. ZHANG’s research interests, have significantly changed and evolved. From 2006 to 2016, sparse representation, dictionary learning and low-rank analysis dominated the area of image restoration and enhancement. Currently, the focus is on deep learning.  Prof. ZHANG said, “Every time new techniques emerge, the field is greatly impacted. If you cannot catch up, you will lag behind your peers and lose the opportunity. Therefore, being open to new techniques and keeping exploration for them are key drivers to produce impactful research outputs.”  Looking ahead, the computing resources required for artificial intelligence (AI) research also bring many challenges. Nevertheless, Prof. ZHANG added the honour of being a highly cited researcher is a driver to think more and explore deeper to create innovative solutions and excel in technological development.   Research Interests: Computer Vision, Image/Video Processing, Pattern Recognition Highly Cited Researcher: 2015-2022 (Clarivate Analytics) Selected Highly Cited Publications: K.

PolyU Project Receives Higher Education Outstanding Scientific Research Output Award from the Ministry of Education

Scientific research on air quality conducted by researchers of The Hong Kong Polytechnic University (PolyU) has received the Higher Education Outstanding Scientific Research Output Award (Science and Technology) 2022.  Led by Prof. Tao WANG, Chair Professor of Atmospheric Environment in the Department of Civil and Environmental Engineering at PolyU, the project entitled “Atmospheric Chemistry of Reactive Nitrogen Oxides and its Impacts on Regional Atmospheric Environment” has been bestowed the Second-Class Award in Natural Science. The Awards from the Ministry of Education aim to recognize outstanding contributions made by researchers towards advancing scientific and technological development.  Prof. WANG, said, “This achievement inspires us to strive for outstanding research and efforts towards enhancing air quality in Hong Kong, the Greater Bay Area and China.” The research started 20 years ago with systemic study on nitrogen oxides in Hong Kong and other places in China.  Nitrogen oxides (NOx), comprising nitric oxide (NO) and nitrogen dioxide (NO2), are mainly produced through high-temperature combustion in road vehicles, ships, and fossil-fuel-powered electricity generation facilities. NOx undergoes chemical reactions to form the so-called secondary pollutants such as ozone and PM2.5. Therefore, understanding the atmospheric dynamics of NOx is crucial to developing strategies for mitigating NO2, ozone and PM2.5 pollution.  By employing field observations, laboratory experiments and computer simulations in the research, Prof. WANG’s team discovered important chemical processes of NOx and their roles in photochemical and haze pollution. The findings have enhanced the knowledge on atmospheric chemistry and also improved an extensively used air quality model for global air quality forecasting and research.  Prof. WANG has made significant contributions to scientific research on sustainable development, with research focus on the origin, transformation and destiny of air pollutants, and their implications on air quality management. The awarded project is Prof. WANG’s core research area, and it is conducted in collaboration with Shandong University, Nanjing University and Chinese Research Academy of Environmental Sciences.
