Object Detection

Definition

Object detection is a computer vision technology that identifies and locates objects within images or video frames. This process involves classifying these objects into predefined categories and determining their positions through bounding boxes, which helps in various applications, especially in photo and video editing. By accurately detecting objects, this technology enhances editing workflows, enables targeted effects, and facilitates content-aware editing features.
