Exam AI-102 topic 2 question 14 discussion

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.

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.

Yes is CORRECT because the code will display the name of each detected brand with a confidence equal to or higher than 75 percent. The if condition checks if brand.Confidence is greater than or equal to 0.75, and if so, it prints the brand name along with its coordinates Yes is CORRECT. The properties brand.Rectangle.X and brand.Rectangle.Y represent the X and Y coordinates of the top-left point of the area, respectively. No is CORRECT because the code does not directly display the coordinates for the bottom-right corner of the rectangle. It displays the coordinates for the top-left corner (brand.Rectangle.X, brand.Rectangle.Y) and the width (brand.Rectangle.W) and height (brand.Rectangle.H). The bottom-right corner coordinates are not explicitly calculated or displayed.

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
