Which of the following is NOT a main feature of Azure Computer Vision?

• A. Optical character recognition (OCR)
• B. Text translation services
• C. Image analysis
• D. Spatial analysis

Answer: (B)

The reasoning for identifying text translation services as not a main feature of Azure Computer Vision lies in the specific focus and capabilities of the Computer Vision service itself. Azure Computer Vision primarily offers functionalities that revolve around processing and analyzing visual content, which include optical character recognition (OCR) to extract text from images, image analysis for identifying objects, scenes, and other characteristics, as well as spatial analysis for understanding spatial relationships among detected objects within imagery.

Text translation services are more aligned with Azure's cognitive services related to natural language processing, specifically under the Translator service. This service is designed to convert text from one language to another, which is distinct from the functionalities offered by Computer Vision, which specializes in image and video content processing. Thus, while translating text is a valuable capability, it does not fall within the core objectives of Azure Computer Vision, making it the correct distinction in this context.
