Preface

The 2021 International Conference on Sensing Technology and Applications (ICSTA 2021) was held on April 23-25, 2021 as a virtual conference due to the growing concerns over the coronavirus outbreak (COVID-19), and in order to protect the well-being of our attendees, partners, and staff as our number one priority. The meeting focused on the research fields of “Sensing Technology” and “Sensing Applications”. The aim is to provide a common forum for researchers, scientists, engineers and practitioners throughout the world to present their latest research findings, ideas, developments and applications in the area of sensing technology, to explore the development path of ecological civilization construction, and to cope with new opportunities and challenges. This scientific event brings together more than 50 national and international researchers in sensing technology and applications. On top of the local participants coming from different national universities, international participants are also registered from different countries, namely USA, Vietnam, India and Egypt. During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In the second part, we invited six professors as our keynote speakers. Prof. Bingguo Liu, from Harbin Institute of Technology, China, delivered a wonderful speech: On-line Vision Inspection technology for high-power laser drivers of inertial confinement fusion. And then we had Prof. Chengying Yang, from University of Taipei, Dept. of Computer Science. He shared a speech on his specialty related to Smartphone Based Tracking System Applied within the Classroom. Prof. Zhi Gao, from Wuhan University, China. His speech title was Vision for Intelligent systems and Intelligent Systems based Vision. In this talk, advanced techniques of these two aspects were introduced, including bio-inspired motion estimation, localization in challenging environments, and target detection. Prof. Yang Chai is an Associate Professor at the Hong Kong Polytechnic University. He shared a speech: Near-sensor and in-sensor computing for neuromorphic machine vision. Prof. Qingyang Wei, from University of Science
