Talk Title: Computational Imaging with Photon Streams
Abstract: Among the yearly iterations on smartphone cameras and advances in sensor design, a key question emerges: what does the future's ultimate camera look like? In this presentation, I will explore the advanced capabilities of single-photon cameras, which have evolved from specialized scientific tools to being integral components in consumer devices like the iPhone. These cameras are not just sensitive; they are exceptionally precise, capable of detecting individual photons and their arrival times to the trillionth of a second. Traditionally, research in this field has focused on simple methods like counting or creating histograms of photons. My work, however, focuses on the raw 'photon stream' output – a sequence of photon arrival times that offers a rich, yet underexplored, source of data. By developing innovative mathematical models and algorithms, I open up exciting new possibilities, such as capturing high-speed videos at standard (30 Hz) and extremely high frame rates (>200 GHz), unveiling hidden 3D structures using multiply scattered light, and achieving micrometer-scale 3D imaging. I will discuss the remarkable capabilities of single-photon cameras and their potential to revolutionize various fields.
Biography: Sotiris Nousias is a Postdoctoral Fellow at the University of Toronto, advised by Kyros Kutulakos. His research interests lie in the fields of computational imaging, computer vision, and signal processing, with a focus on single-photon imaging. His aim is to push the boundaries of imaging, developing novel systems and algorithms that can reveal the world in entirely new ways. He earned his PhD from University College London, advised by Christos Bergeles. His research has been recognized with best paper awards at two of the leading computer vision conferences: CVPR in 2019 and ICCV in 2023.

Speaker: Dr. Zili Meng, Assistant Professor, Hong Kong University of Science and Technology (HKUST)
Talk Title: Transport Layer Innovations in Ultra-Low Latency Video Streaming
Abstract: In the post-pandemic era, ultra-low latency video streaming is increasingly popular nowadays. Numerous applications like videoconferencing, cloud gaming, virtual reality, remote driving are coming or have come to our daily life. However, these interactive video streaming applications require ultra-low and consistent latency to ensure the interactive experience, which challenges how the sender is transmitting packets and reacting to fluctuations nowadays.
My research rethinks the latency in interactive video streaming in an end-to-end way and tries to share some preliminary thoughts on what the network and related communities should do to enable the wide deployment of these applications. In this talk, I will present our work on how to achieve a consistent low latency for interactive video streaming. Specifically, I will talk about how we control the tail latency on the transport layer from the perspective of congestion control (Zhuge, SIGCOMM'22) and loss recovery (Hairpin, NSDI'24).
Biography: Zili Meng is an assistant professor at HKUST. He received his B.Eng. (Hons) and Ph.D. (Hons) from Tsinghua University. His current research interest focuses on ultra-low latency interactive streaming from all layers. He is the recipient of the Doctoral Dissertation Awards from ACM China and China Institute of Electronics. a Microsoft PhD Fellowship (Asia), the Gold Medal of SIGCOMM 2018 SRC, and some best paper awards. His research has been used in many industry companies.
