内容摘要Abstract：

 Visual computing,traditionally,is a generic term for all computer science disciplines dealing with various types of visual data including images,videos,and other types of visual data.Over the past few decades, visual computing has witnessed its paradigm-shifting evolution from pure algorithm development to overall system design.This talk shall start with an analysis of the evolution of contemporary visual computing systems from several systematic perspectives.Such analysis shall be closely coupled with the chronological reflection of my career journey over the past 40 years.At the beginning of my academic career in the 1980s and 1990s,visual computing research was mostly carried out as algorithm development for processing and analyzing a single modality of visual data.During the 2000s,my research shifted to the integrated design of algorithms and systems,when pursuing trailblazing research in joint source and channel coding for wireless video and large-scale wireless sensor networks.During the 2010s,my research has focused on human-centric mobile visual computing systems in which both mobile device constraints and human perception principles need to be carefully balanced at the system level design to achieve desired quality-of-experiences (QoE)when massive consumers are using smartphones and other portable devices for both working and personal purposes.In recent years,my research in contemporary visual computing has evolved beyond conventional visual computing by embracing multimodal artificial intelligent systems as exampled by the Internet of Video Things (loVT)and vision-language integration via Large Language Model (LLM)for the 6G semantic communications.
