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 este o colecție de toolkit-uri specializate care oferă motoare pentru geometrie, viziune artificială, matematică, simulare fizică și procesarea semnalelor. Funcționează ca o bibliotecă cuprinzătoare de matematică și fizică axată pe algebră liniară, optimizare numerică și calcule geometrice pentru aplicații tehnice. Proiectul se distinge printr-un toolkit de simulare fizică și un motor de geometrie 3D. Acestea oferă capabilități pentru integrare Verlet, solvere iterative de cinematică inversă, randare de câmpuri de distanță prin raymarching volumetric și deformarea geometriei mesh-urilor. Include, de asemenea, un utilitar de viziune artificială pentru estimarea mișcării relative a camerei și generarea de proiecții fisheye. Biblioteca acoperă arii largi de capabilități, inclusiv sisteme de detectare a coliziunilor folosind diferențe Minkowski și hashing spațial, planificarea mișcării în robotică și procesarea semnalelor pentru reducerea zgomotului folosind filtre Kalman. Funcționalitatea suplimentară include optimizarea datelor numerice, operații de algebră liniară pentru potrivirea seturilor de puncte și serializare JSON bazată pe reflexie pentru ierarhiile de obiecte.
