AI-102 Implement computer vision solutions Practice Question
You are developing a solution that uses Azure AI Vision to analyze images of products on an assembly line. You need to detect whether each product has a specific logo and also read the serial number printed on it. Which two Azure AI Vision services should you use? (Choose two.)
⚠ Common exam trap
The trap here is assuming that a single service like Document Intelligence can handle both tasks, but it is not designed for logo detection on products.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure AI Custom Vision
To detect a specific logo and read a serial number, you need two distinct capabilities: custom object detection and text extraction. Custom Vision can be trained to recognize the logo, while the Read API extracts the serial number from the image. Together, they fulfill both requirements without unnecessary complexity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure AI Custom Vision
Why this is correct
Custom Vision allows you to train a custom image classifier or object detector to recognize specific logos. You can label images of products with and without the logo, train a model, and then use it to detect the presence of the logo on new images. This meets the requirement to detect whether each product has the specific logo.
- ✓
Azure AI Vision Read API
Why this is correct
The Read API is optimized for extracting printed and handwritten text from images. It can accurately read serial numbers printed on products, even if they are in different fonts or slightly rotated. It returns the text and bounding boxes, which you can then parse to extract the serial number. This directly addresses the requirement to read the serial number.
- ✗
Azure AI Document Intelligence
Why it's wrong here
Document Intelligence is designed for extracting structured data from documents like invoices and receipts, not for logo detection on products. While it can read text, it is not optimized for reading serial numbers on physical products in an assembly line context. It also lacks logo detection capabilities, making it unsuitable for this scenario.
- ✗
Azure AI Vision Spatial Analysis
Why it's wrong here
Spatial Analysis is used for analyzing movement in video streams, such as counting people or tracking their positions. It does not perform logo detection or text recognition on static images. It would not help in identifying logos or reading serial numbers on products, as its purpose is entirely different.
- ✗
Azure AI Face API
Why it's wrong here
The Face API is designed for detecting and recognizing human faces, not logos or text. It cannot identify logos or read serial numbers. Using it for this scenario would not provide any relevant information, as it focuses on facial attributes and identification, which are unrelated to product inspection tasks.
