HOTSPOT -
You are developing an application that will use the Computer Vision client library. The application has the following code.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:
Box 1: No -
Box 2: Yes -
The ComputerVision.analyzeImageInStreamAsync operation extracts a rich set of visual features based on the image content.
Box 3: No -
Images will be read from a stream.
Reference:
https://docs.microsoft.com/en-us/java/api/com.microsoft.azure.cognitiveservices.vision.computervision.computervision.analyzeimageinstreamasync
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.
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.
NYN Box 3: No.... because the image (whether uploaded or a URL), the CODE will read it as a An image STEAM. Please continue reading the same URL you shared.
File.OpenRead is a System.IO method and reads file from the local storage path provided as a parameter hence last one is Y as it reads file from local storage https://learn.microsoft.com/en-us/dotnet/api/system.io.file.openread?view=net-7.0
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
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
Not A Face Recognition, But Analyze the Image (i.e. extract information from the images) Console.write shows, it will return TAG and Confidence File.Openread(localImage) - Will read from local system NO YES 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 Image analysis Return the category and confident score Read local video streaming or streaming source
To me correct answers are NYY. localImage parameter is a string, that's a file path
Answer is NYY
No Yes Yes
No Yes Yes
N - Y - Y

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
