Class-Based Object Tagging API is a service that classifies and tags objects within images or videos based on predefined classes or categories. This API identifies and categorizes objects in visual data according to specific classes, such as vehicles, animals, or people. It provides detailed information about each detected object, including its class label and bounding box coordinates. This classification helps in organizing and managing visual content, enhancing functionalities in areas like inventory management, security monitoring, and automated tagging systems.
