Correct answers: A, C, E
Explanation
The Azure AI Face detection service provides key capabilities such as detecting faces, estimating facial attributes (e.g., age, gender, emotion), and tracking faces across frames in a video, which are essential for analyzing customer behavior in retail settings. However, it does not include features like identifying specific individuals or recognizing objects in the background, as those are separate functionalities provided by other Azure AI services.
- A. Correct.
The Face detection service can detect the presence of faces in an image or video, which is a core capability for analyzing customer behavior.
- B. Incorrect.
Face detection on its own does not identify specific individuals. This requires the Face recognition feature, which is a separate functionality.
- C. Correct.
The Face detection service can estimate attributes like age, gender, and emotion, which are useful for understanding customer demographics and sentiment.
- D. Incorrect.
Recognizing and labeling objects in the background is not a capability of the Face detection service. This is handled by Azure Computer Vision's object detection feature.
- E. Correct.
The Face detection service can track multiple faces across frames in a video, enabling the analysis of movement patterns and customer interactions.
