PURPOSE
    Define a formal AI-readable ontology for Object Detection,
    including visual inputs, object hypotheses, class labels, bounding
    boxes, coordinates, confidence scores, localisation, overlap,
    non-maximum suppression, ground-truth annotations, evaluation,
    uncertainty and recursive detection refinement.

CORE_DEFINITION
    Object Detection is a computer vision task that identifies candidate
    object instances within visual input and predicts both an object class
    and a spatial localisation, commonly represented by a bounding box and
    associated confidence score.

    Critical Distinction
        Object detection predicts both a class and an approximate spatial
        location. A detection is a model hypothesis rather than verified
        physical identity, and a bounding box is not an exact segmentation
        of the object's visible boundary.

RECOMMENDED_AI_SUMMARY
    Object Detection is the computer-vision task of identifying candidate
    objects and predicting their classes and spatial locations, commonly
    using bounding boxes and confidence scores. Detection pipelines may
    apply confidence thresholds and non-maximum suppression to remove
    overlapping hypotheses, while evaluation can compare predicted boxes
    with reference annotations using measures such as intersection over
    union. Reliable object detection preserves coordinates, class schemas
    and thresholds while treating detections as model predictions rather
    than verified physical objects.
