Exam AI-102 topic 2 question 14 discussion

Maybe I take it too literally, but I think the third one is "NO": the response returns Width and Height, which can be used to calculate the coordinates of bottom right corner, but it does not include them directly.

Y, Y, N https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/how-to/shelf-analyze#bounding-box-api-model x Left-coordinate of the top left point of the area, in pixels. y Top-coordinate of the top left point of the area, in pixels. w Width measured from the top-left point of the area, in pixels. h Height measured from the top-left point of the area, in pixels.

yes yes no

I cant see anythig related to corner position in the api. Then its Y, Y, Y

The correct sequence is Yes Yes No.

This is the same question as Topic2 #29.

Yes Yes No

Yes Yes No

The brand_confidence variable is not declared in the snippet. Perhaps they meant brand.confidence? Same with rectangle_x . As it stands, the answers should be N,N,N.

The Python syntax for working with Python dictionaries is wrong. Remember we are calling the API which returns a JSON object. brand.rectangle_x - WRONG - it should be brand.rectangle.x brand_confidence - WRONG - should be brand.confidence So the answer should be N for all!

Final Answer: Yes Yes No

The code will return the name of each detected brand with a confidence equal to or higher than 75 percent. Yes, the code will return the name of each detected brand with a confidence equal to or higher than 75 percent. 2. The code will return coordinates for the top-left corner of the rectangle that contains the brand logo of the displayed brands. Yes, the code will return the coordinates for the top-left corner of the rectangle that contains the brand logo of the displayed brands. 3. The code will return coordinates for the bottom-right corner of the rectangle that contains the brand logo of the displayed brands. No, the code will not return coordinates for the bottom-right corner of the rectangle that contains the brand logo of the displayed brands. The code is printing the width and height of the rectangle instead.

it could be a trap : so yes, no (it is rectangle.x and not _x) , no (should be x + w as the service returns the width and top left corner : Console.WriteLine("Brands:"); foreach (var brand in results.Brands) { Console.WriteLine($"Logo of {brand.Name} with confidence {brand.Confidence} at location {brand.Rectangle.X}, " + $"{brand.Rectangle.X + brand.Rectangle.W}, {brand.Rectangle.Y}, {brand.Rectangle.Y + brand.Rectangle.H}"); } Console.WriteLine(); https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/how-to/call-analyze-image?tabs=csharp

its' yes yes no The coordinates are always regarding the top left point of the rectangle

Y Y Y the code will return the coordinates for any position

yes yes yes
