I am a Lecturer at the University of Reading working on leveraging machine learning to optimise both traditional and immersive media technologies. Previously, I was a postdoc at UCL and did PhD at PUC-Rio. I have experience acting as a team leader or PI in multiple funded research projects (e.g., immersive media, video analysis and interactive TV) and contributed to research communities (ACM SIGMM, SBC WebMedia) and standard committees (ITU-T SG16, Brazilian TV Forum).
Users’ consumption of multimedia content grows exponentially in the Internet, smart devices, social media, and other contexts. Multimedia Systems addresses technological issues for enabling and improving consumption, such as content delivery, adaptation, accessibility and personalisation, and others. See some aspects of my multimedia research below.
Multimedia systems deal with the delivery of multimedia data in digital networks. A multimedia system infrastructure requires components such as protocols, services, middleware, and mechanisms to handle a well-defined quality of service (QoS).
Some of my contributions in the field are in TV middleware:
For me, some important researchers in this field are: 🎓 Klara Nahrstedt 🎓 Christian Timmerer
Immersive media research aims to make multimedia systems more natural and with higher QoE, especially by imitating the physical world through digital simulation. I particularly researched it through VR/360 video and multisensorial aspects.
Some of my contributions in the field are in 360 videos:
For me, some important researchers in this field are: 🎓 Pablo Cesar, CWI, 🎓 Jesús Gutiérrez 🎓 Cornelius Hellge
Video Understanding deals with how computers can gain high-level understanding from digital images or videos. Unlike Multimedia Systems’ aspects of delivery and feasibility, it aims to analyse multimedia data automatically. Usage scenarios are video retrieval and browsing, anomaly detection, and others.
Some of my contributions in the field are unsupervised video analysis:
For me, some important researchers in this field are: 🎓 Richard Szeliski 🎓 Shaogang Gong
I truly believe technology can be a vehicle for social impact, especially in multimedia. Today, multimedia/web/video data are spread and are useful for accessibility, governance transparency, minority inclusion, social justice/activism, etc.
