Scene Graph

A scene graph is a structured model that represents the objects within a visual scene and the relationships between them. Think of it as a detailed map where each item, like a person, table, or car, is a node, and the connections show how these objects relate, such as "sitting on" or "next to." Scene graphs help computers understand and interpret images or videos by organizing the elements and their interactions, enabling applications like image recognition, scene understanding, and augmented reality. They provide a clear, systematic way to represent complex visual information.
