Exam AI-102 topic 2 question 1 discussion

Box 3 is Yes, the stream will be generated from a local image!

Box 3 should be Yes, a stream is only a pathway for data. and in this case the data actually comes from a local file. The correct answer would be No, Yes, Yes.

1. **The code will perform face recognition.** **Answer:** No The code uses the `ComputerVisionClient` to analyze an image for visual features such as `Description` and `Tags`, not for face recognition. 2. **The code will list tags and their associated confidence.** **Answer:** Yes The code retrieves tags and their confidence scores from the `results.Tags` property and outputs them. 3. **The code will read a file from the local file system.** **Answer:** Yes The code uses `File.OpenRead(localImage)` to read an image file from the local file system.

N - Y - Y

The code will perform face recognition --> No The code will list tags and their associated confidence --> Yes The code will read a file from the local file system --> Yes

The code will perform face recognition. No. The code is set to analyze image descriptions and tags (VisualFeatureTypes.Description, VisualFeatureTypes.Tags), but it does not include face recognition. The code will list tags and their associated confidence. Yes. The code includes a loop that iterates through results.Tags and prints each tag's name and confidence. The code will read a file from the local file system. Yes. The code uses File.OpenRead(localImage) to open and read an image file from the local file system. So, the answers are: The code will perform face recognition. No The code will list tags and their associated confidence. Yes The code will read a file from the local file system. Yes

No Yes Yes

No Yes Yes Image analysis Return the category and confident score Read local video streaming or streaming source

The fact that the parameter is named 'local', might be misleading - it could be anything. HOWEVER, I'm not a C# expert, but File.OpenRead tells us that the file is on a filesystem to which the device has access. SO my vote is NYY

Final Answer: N Y Y

To me correct answers are NYY. localImage parameter is a string, that's a file path

NYY is the answer. https://learn.microsoft.com/en-us/java/api/com.microsoft.azure.cognitiveservices.vision.computervision.computervision?view=azure-java-legacy#com-microsoft-azure-cognitiveservices-vision-computervision-computervision-analyzeimageinstreamasync(byte-()-analyzeimageinstreamoptionalparameter) his operation extracts a rich set of visual features based on the image content. Two input methods are supported (1) Uploading an image or (2) specifying an image URL.

Box 1: No. The code generates description and tags. See line 3,4 Box 2: Yes. The code displays tag.Name and tag.Confidence Box 3: Yes. File.OpenRead reads a local file. See https://docs.microsoft.com/en-us/dotnet/api/system.io.file.openread?view=net-6.0

No Yes Yes

Answer is NYY
