I think the answer is text extraction
Since the goal is to extract the vehicle registration numbers from the CCTV footage, text extraction using OCR algorithms would be the most appropriate choice. OCR algorithms can recognize and extract text information from images, making it possible to retrieve the registration numbers from the captured video frames. This enables automated monitoring and analysis of the traffic data by extracting the relevant textual information.
The cars are already detected from the CCTV footage, you are asked here what service to use to extract license plate information, which is text extraction using OCR.
Correct answer is text extraction , the only way to collect registration number is OCR which is text extraction, object detection is useful to find a car
A traffic monitoring system that collects vehicle registration numbers from CCTV footage is an example of "text extraction" in the Computer Vision service. Text extraction, specifically optical character recognition (OCR), is the process of recognizing and extracting alphanumeric characters from images or video frames. In the context of a traffic monitoring system, OCR algorithms can be applied to extract the registration numbers from the license plates captured in the CCTV footage. This enables automated data collection and analysis of vehicle registration information for traffic monitoring and related purposes.
A traffic monitoring system that collects vehicle registration numbers from CCTV footage is an example of text extraction in the Computer Vision service. Text extraction is the process of identifying and extracting text from images, which includes tasks like recognizing license plate numbers in the context of vehicle registration numbers. Image classification, object detection, and spatial analysis are different types of computer vision tasks that focus on categorizing or locating objects in images but not necessarily extracting textual information.
The answer should be text extraction.
OCR or Optical Character Recognition is also referred to as text recognition or text extraction.

I would choose text extraction as it falls under Computer Vision - Image Analysis service - see example here: https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/concept-ocr#text-extraction-example
