This project is an educational suite and technical guide designed for mastering video codecs and signal processing. It provides a structured curriculum through an engineering course, interactive labs, and tutorials focused on the fundamental principles of video compression and digital signal processing. The resource includes a technical guide for analyzing specific codecs like AV1, VP9, and H.265. It distinguishes itself by providing a containerized media lab, which ensures a consistent development environment for experimenting with video technology tools and notebooks. The project covers a
Identifies and encodes changes between sequential video frames using block motion compensation and motion vectors.
SAMURAI is a zero-shot visual tracking model that adapts the Segment Anything architecture for video object segmentation. It uses a first-frame prompt, such as a bounding box or mask, to initialize tracking, then employs a motion-aware memory mechanism that stores and updates temporal motion features across frames to guide mask refinement. An online memory update strategy continuously refreshes this memory with new frame predictions, while temporal motion encoding computes optical flow between consecutive frames to inform object boundary and occlusion handling. The system is designed for real
Computes optical flow between consecutive frames to inform object boundary and occlusion handling.
OpenCVSharp is a .NET library that wraps native OpenCV functions, providing C# developers with access to OpenCV's computer vision capabilities through an API that mirrors the native C/C++ style. It serves as a managed wrapper for image processing, feature detection, object detection, and image manipulation tasks, while also handling automatic disposal of unmanaged OpenCV resources like Mat objects to prevent memory leaks in .NET applications. The library enables keypoint detection and descriptor extraction using algorithms such as AKAZE, BRISK, or FAST, with brute-force or FLANN-based matchin
Implements dense optical flow estimation using the Brox variational method for motion analysis.
MathUtilities ist eine Sammlung spezialisierter Toolkits, die Engines für Geometrie, Computer Vision, Mathematik, Physiksimulation und Signalverarbeitung bereitstellen. Sie fungiert als umfassende Mathematik- und Physikbibliothek mit Fokus auf lineare Algebra, numerische Optimierung und geometrische Berechnungen für technische Anwendungen. Das Projekt zeichnet sich durch ein Physiksimulations-Toolkit und eine 3D-Geometrie-Engine aus. Diese bieten Funktionen für Verlet-Integration, iterative Inverse-Kinematik-Solver, Distance-Field-Rendering mittels volumetrischem Raymarching und Mesh-Geometrie-Deformation. Es enthält zudem ein Computer-Vision-Dienstprogramm zur Schätzung der relativen Kamerabewegung und zur Generierung von Fisheye-Projektionen. Die Bibliothek deckt breite Funktionsbereiche ab, darunter Kollisionserkennungssysteme mittels Minkowski-Differenzen und Spatial Hashing, Robotik-Bewegungsplanung und Signalverarbeitung zur Rauschunterdrückung mittels Kalman-Filtern. Zusätzliche Funktionen umfassen numerische Datenoptimierung, Operationen der linearen Algebra für Point-Set-Fitting und reflexionsbasierte JSON-Serialisierung für Objekthierarchien.
