Microsoft Azure AI Fundamentals (AI-900) Practice Exam

What technology is specifically used to interpret text from images?

1. Object detection

2. Image classification

3. Optical character recognition (OCR)

4. Facial recognition

The correct answer is: Optical character recognition (OCR)

Optical character recognition (OCR) is the technology specifically designed to interpret and extract text from images. It utilizes various algorithms and machine learning techniques to analyze the shapes and patterns of the characters found in images, such as photographs of documents, handwritten notes, or any other visual representation of text. Once OCR processes the image, it generates machine-readable text, making it useful for digitizing printed documents, automating data entry, and improving accessibility for the visually impaired. While object detection, image classification, and facial recognition serve important roles in computer vision, they focus on different tasks. Object detection identifies and locates items or objects within an image, image classification categorizes images based on their content, and facial recognition identifies or verifies individuals based on their facial features. These technologies do not specifically interpret text, hence distinguishing OCR as the appropriate solution for extracting textual information from images.
