Returning a bounding box that indicates the location of a vehicle in an image is an example of which type of AI technique?

1. Image classification

2. Object detection

3. Feature extraction

4. Facial recognition

The correct answer is: Object detection

The task of returning a bounding box that indicates the location of a vehicle in an image is a clear application of object detection. Object detection techniques go beyond simply identifying what objects are present in an image (which is what image classification does); they also determine the precise location of those objects. In this case, the bounding box provides specific coordinates that define where the vehicle is located within the image, highlighting the concept of spatial awareness inherent in object detection. This is different from image classification, which merely figures out what is in the image without indicating where objects are positioned. Feature extraction involves identifying and quantifying features within an image to help in understanding or classifying the image, but it does not return positional data like bounding boxes do. Facial recognition is a specific application focused on identifying or verifying individuals based on their facial features, rather than locating objects like vehicles. Thus, object detection is the most appropriate classification for the task described.
