You need to create a model that labels a collection of your personal digital photographs. Which Azure Cognitive Services service should you use?

Azure AI Form Recognizer (now Document Intelligence) is used for extracting data and structure from documents and forms, not for general custom image labeling.

Azure AI Custom Vision is specifically designed for users to build, deploy, and improve custom image classification or object detection models tailored to their own unique datasets and labeling criteria, making it ideal for personal photograph categorization.

Azure AI Language is a service for natural language processing tasks, such as text analysis or sentiment analysis, not for image processing or labeling.

Azure AI Computer Vision provides pre-trained capabilities like image tagging, captioning, and OCR, but for highly specific, user-defined labels on personal photographs, Custom Vision offers a more targeted and trainable solution.
