Answer
D. Optical character recognition (OCR).
Explanation
Optical Character Recognition, or OCR, is the artificial intelligence technology that enables computer systems to extract text from handwritten or printed documents and images. OCR works by analyzing the patterns of light and dark in an image to identify individual characters, numbers and symbols, which it then converts into machine-readable text.
The key steps in the OCR process are:
- Pre-processing the image to optimize contrast, remove noise, and correct any distortions
- Segmenting the image into lines and characters
- Recognizing each character by comparing it to stored patterns
- Post-processing to apply linguistic knowledge and correct errors
Through sophisticated machine learning algorithms, modern OCR systems can achieve high accuracy even with handwritten text in various styles. This capability has many important applications, such as:
- Digitizing paper documents and records to enable searching, editing and analysis
- Automating data entry from forms and surveys
- Making printed books and articles accessible to blind and visually impaired users
- Extracting text from images for translation, indexing or republishing
In summary, Optical Character Recognition is the AI technology that makes it possible to extract text from handwritten and printed documents, enabling many valuable applications. Understanding OCR is important for the AI-900 Microsoft Azure AI Fundamentals certification, which tests knowledge of core AI concepts and Azure cognitive services.
OCR is the process of extracting text from images, including printed or handwritten documents. It recognizes and converts text into a machine-readable format.
