multiobject

Multiobject is a general, non-technical term used across several disciplines to denote systems, models, or methods that operate on or reason about more than one object at a time. Because there is no single formal definition, its precise meaning depends on the domain, but a common thread is the management or analysis of collections of objects rather than a single entity.

In computer vision and robotics, multiobject processing refers to tasks such as multi-object detection and tracking, where algorithms must identify and maintain identities of several objects across frames. Techniques include data association, Kalman filtering, and deep learning-based detectors. In 3D graphics and scene description, a multiobject representation describes a scene as an assembly of individual objects, each with geometry, materials, and relationships, often organized in a scene graph.

In software engineering and databases, multiobject concepts appear in programs that manipulate many instances, and in object stores or object-relational databases that retrieve collections of objects based on queries. Performance, concurrency, consistency, and lifecycle management are common concerns when handling many objects.

The term also appears in related areas such as multiobject tracking and, more broadly, multiobject optimization, where several objects or candidates are considered simultaneously to achieve multiple goals. See also: object, scene graph, MOT, object database, object-oriented programming.
