Speech Title: SDP-Based Multiple-View Triangulation
Abstract: A key problem in computer vision consists of estimating the position in the scene of a point from the available estimates of its image projections on several cameras and the calibration parameters. This problem, known as multiple-view triangulation, has received a number of contributions given its importance. This talk explains how semidefinite programming, an area of convex optimization, can be exploited to address this problem in the common case where the reprojection error to be minimized is measured through the L2 norm. In particular, two methods are presented, one suitable for real time applications based on the fundamental matrices relating each pair of views, and the other more accurate based on the projection matrices that characterize each view. Both methods provide an estimate of the sought scene point together with a certificate of optimality. The talk also explains how occlusions can be considered in the presented framework.

Speech Title: Human-Robot Collaboration via Control Barrier Functions and Optimization
Abstract: Human–robot collaboration (HRC) has emerged as a cornerstone for the next generation of intelligent manufacturing, service robotics, and human-centric automation. Unlike traditional industrial robots confined to isolated tasks, collaborative robots must share workspace, goals, and decision-making processes with humans, requiring real-time safety, adaptability, and efficiency. One of the challenges for multi-robot systems and human-robot systems is the design of effective algorithms that enable the robots to work cooperatively and safely with other robots or humans. Optimization provides a unifying mathematical framework to formalize these challenges. This talk will first give a brief review on human-robot collaboration, and then present some recent related research results.
