Exam AI-102 topic 2 question 3 discussion

The second one should be generate Thumbnail imho.

Both answers are incorrect. The correct answers are: https://contoso1.cognitiveservices.azure.com/ AND generateThumbnail westus.dev.cognitive.microsoft.com wouldn't be a correct Computer Vision endpoint if the resource name is contoso1. Also, per the documentation, areaOfInterest "returns a bounding box around the most important area of the image", it doesn't return a different size photo (https://docs.microsoft.com/en-us/rest/api/computervision/3.1/get-area-of-interest).

"West US Azure region" --> https://westus.api.cognitive.microsoft.com "smart cropping " --> generateThumbnail https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/concept-generating-thumbnails

POST https://westus.api.cognitive.microsoft.com/vision/v3.2/generateThumbnail?width=500&height=500&smartCropping=True { "url": "{url}" }

1. contoso1 2. gererateThumbnail

Final Answer: 1. https://contoso1.cognitiveservices.azure.com/ 2. generateThumbnail

API URL: The base URL for the Analyze Image 4.0 API is typically: https://<region>.api.cognitive.microsoft.com/vision/v4.0/analyze Replace <region> with the appropriate Azure region (in this case, West US).

"You need to use contoso1 to make a different size of a product photo by using the smart cropping feature." -> You need to use contoso1 to make.... that is hosted in the west us....

1. https://contoso1.cognitiveservices.azure.com 2. generateThumbnail https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-generating-thumbnails A thumbnail is a reduced-size representation of an image. Thumbnails are used to represent images and other data in a more economical, layout-friendly way. The Computer Vision API uses smart cropping to create intuitive image thumbnails that include the most important regions of an image with priority given to any detected faces. The Computer Vision thumbnail generation algorithm works as follows: - Remove distracting elements from the image and identify the area of interest—the area of the image in which the main object(s) appears. - Crop the image based on the identified area of interest. - Change the aspect ratio to fit the target thumbnail dimensions.

I simulated this in Azure Portal: 1. endpoint is https://contoso1.cognitiveservices.azure.com/ 2. thumbnail

https://contoso1.cognitiveservices.azure.com/ is correct. Context from ChatGPT: westus.api.cognitive.microsoft.com is also a valid endpoint for the Cognitive Services APIs, including the Computer Vision API. However, it is important to note that this endpoint is deprecated and will be retired on October 31, 2024. Therefore, it is recommended to use the newer endpoint format https://<resource-name>.cognitiveservices.azure.com/ for any new development work. This endpoint format follows a more standard Azure resource URL pattern and is also more flexible in terms of geographic distribution and availability. Hope it helps.

The first is https://contoso1.cognitiveservices.azure.com the second is generateThumbnail POST https://*.cognitiveservices.azure.com/vision/v3.2/generateThumbnail?width=100&height=100&smartCropping=true&model-version=latest HTTP/1.1 Host: *.cognitiveservices.azure.com Content-Type: application/json {"url":"http://example.com/images/test.jpg"}

on my exam (2023-01-16 Passed) My Answer: https://westus.api.cognitive.microsoft.com But I think this is wrong.Because Question request use contoso1! So correct answer is : https://contoso1.cognitiveservices.azure.com/

Westus generateThumbnail https://docs.microsoft.com/en-gb/azure/cognitive-services/computer-vision/how-to/generate-thumbnail#call-the-generate-thumbnail-api curl -H "Ocp-Apim-Subscription-Key: <subscriptionKey>" -o <thumbnailFile> -H "Content-Type: application/json" "https://westus.api.cognitive.microsoft.com/vision/v3.2/generateThumbnail?width=100&height=100&smartCropping=true" -d "{\"url\":\"https://upload.wikimedia.org/wikipedia/commons/thumb/5/56/Shorkie_Poo_Puppy.jpg/1280px-Shorkie_Poo_Puppy.jpg\"}"

First one is contoso.cognitive services. Just checked my own script and cognitiive services uses ur rg name in the endpoint URI.

For first dropdown, 3rd option works with cognitive service key and computer vision key as well. whereas 2nd option works with only computer vision key. so answer 3rd works in both situation. therefor i'll go with https://westus.api.cognitive.microsoft.com/vision/v3.1/generateThumbnail?width=500&height=500&smartCropping=True
