This study introduces a novel framework for the automatic two-dimensional tracking of padel games using monocular recordings. By integrating advanced computer Vision and Deep Learning techniques, our algorithm detects and tracks players, the court, and the ball. Through homography, we accurately project detected player positions onto a two-dimensional court, enabling comprehensive tracking throughout the game. We tested the proposed algorithm using amateur video recordings of padel games found in literature. This approach remains user-friendly, cost-effective, and adaptable to various camera angles and lighting conditions. This makes it accessible to both amateur and professional players and coaches, providing a valuable tool for performance analysis. Additionally, the proposed framework holds potential for adaptation to other sports with minimal modifications, further broadening its applicability.

Hyperproperties are system properties that relate multiple execution traces and occur, e.g., when specifying security and information-flow properties. Checking if a hyperproperty is satisfiable has many important applications, such as testing if some security property is contradictory, or analyzing implications and equivalences between information-flow policies. In this paper, we present FOLHyper, a tool that can automatically check satisfiability of hyperproperties specified in the temporal logic HyperLTL. FOLHyper reduces the problem to an equisatisfiable first-order logic (FOL) formula, which allows us to leverage FOL solvers for the analysis of hyperproperties. As such, FOLHyper is applicable to many formulas beyond the decidable there exists(*)for all(*) fragment of HyperLTL. Our experiments show that FOLHyper is particularly useful for proving that a formula is unsatisfiable, and complements existing bounded approaches to satisfiability.
