In the context of computer vision, what term describes the systematic analysis of an image to detect specific objects?

1. Facial recognition

2. Object detection

3. Classification

4. Optical character recognition (OCR)

The correct answer is: Object detection

The term that describes the systematic analysis of an image to detect specific objects is object detection. This process involves identifying and locating multiple objects within an image and often includes drawing bounding boxes around those objects alongside classifying them. For instance, in an image of a street, object detection would allow a system to identify and locate cars, pedestrians, traffic lights, and more. Facial recognition primarily focuses on identifying and verifying human faces within images, which is a specialized form of object detection aimed specifically at faces rather than various objects in a scene. Classification, on the other hand, involves categorizing an entire image into a single label or class without necessarily locating individual objects. Optical character recognition (OCR) specifically pertains to recognizing text within images and converting it into machine-readable formats, rather than identifying various objects. Thus, object detection is the most accurate term for the described process of analyzing an image to recognize various specific objects.
