TURBO: Utility-Aware Bandwidth Allocation for Cloud-Augmented Autonomous Control

Authors: Peter Schafhalter, Alexander Krentsel, Hongbo Wei, Joseph E. Gonzalez, Sylvia Ratnasamy, Scott Shenker, and Ion Stoica

Published in: OASIcs, Volume 139, 1st New Ideas in Networked Systems (NINeS 2026)

Abstract
Autonomous driving system progress has been driven by improvements in machine learning (ML) models, whose computational demands now exceed what edge devices alone can provide. The cloud offers abundant compute, but the network has long been treated as an unreliable bottleneck rather than a co-equal part of the autonomous vehicle control loop. We argue that this separation is no longer tenable: safety-critical autonomy requires co-design of control, models, and network resource allocation itself. We introduce TURBO, a cloud-augmented control framework that addresses this challenge, formulating bandwidth allocation and control pipeline configuration across both the car and cloud as a joint optimization problem. TURBO maximizes benefit to the car while guaranteeing safety in the face of highly variable network conditions. We implement TURBO and evaluate it in both simulation and real-world deployment, showing it can improve average accuracy by up to 15.6%pt over existing on-vehicle-only pipelines. Our code is made available at www.github.com/NetSys/turbo.

07171 Abstracts Collection – Visual Computing – Convergence of Computer Graphics and Computer Vision

Authors: Markus Gross, Heinrich Müller, Hans-Peter Seidel, and Harry Shum

Published in: Dagstuhl Seminar Proceedings, Volume 7171, Visual Computing - Convergence of Computer Graphics and Computer Vision (2008)

Abstract
From 22.04. to 27.04.2007, the Dagstuhl Seminar 07171 ``Visual Computing - Convergence of Computer Graphics and Computer Vision'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

07171 Summary – Visual Computing – Convergence of Computer Graphics and Computer Vision

Authors: Markus Gross, Heinrich Müller, Hans-Peter Seidel, and Harry Shum

Published in: Dagstuhl Seminar Proceedings, Volume 7171, Visual Computing - Convergence of Computer Graphics and Computer Vision (2008)

Abstract
Due to the importance of visual information for humans, visual computing is at the very core of the technologies enabling the modern information society. New and emerging technologies such as multimedia, digital television, telecommunication and telepresence, or virtual reality further indicate the tremendous potential of visual interaction with computers in the years to come. Typical for the field is the coincidence of very large data sets with the demand for fast, if possible interactive, user-adapted high quality visual display of the results. Furthermore, the user should be able to interact with the environment in a natural and intuitive way. In order to address the challenges mentioned above, a new and more integrated scientific view of Visual Computing is required that unifies the previously separate ''visual'' disciplines of computer graphics and computer vision. Computer graphics is traditionally concerned with generating visual interfaces of computers and applications to the user. Computer vision focuses on enabling computers to understand and interpret visual information from static images and video sequences.

Image-Based Motion Compensation for Structured Light Scanning of Dynamic Surfaces

Authors: Stefan Gumhold and Sören König

Published in: Dagstuhl Seminar Proceedings, Volume 7171, Visual Computing - Convergence of Computer Graphics and Computer Vision (2008)

Abstract
Structured light scanning systems based on temporal pattern codification produce dense and robust results on static scenes but behave very poorly when applied to dynamic scenes in which objects are allowed to move or to deform during the acquisition process. The main reason for this lies in the wrong combination of encoded correspondence information because the same point in the projector pattern sequence can map to different points within the camera images due to depth changes over time. We present a novel approach suitable for measuring and compensating such kind of pattern motion. The described technique can be combined with existing active range scanning systems designed for static surface reconstruction making them applicable for the dynamic case. We demonstrate the benefits of our method by integrating it into a gray code based structured light scanner, which runs at thirty 3d scans per second.
