PTI.Microservices.Library.AzureComputerVision

Facilitates the consumption of the APIs in Azure Computer Vision

Examples:

Note: The examples below are passing null for the logger, if you want to use the logger make sure to pass the parameter with a value other than null

Describe Image

CustomHttpClient customHttpClient = new CustomHttpClient(new CustomHttpClientHandler(null));
AzureComputerVisionService azureComputerVisionService =
   new AzureComputerVisionService(null, this.AzureComputerVisionConfiguration,
   customHttpClient);
Stream imageStream = (await new HttpClient().GetStreamAsync(this.TestFaceImageUrl));
var result = await azureComputerVisionService.DescribeImageAsync(imageStream,
Path.GetFileName(this.TestComputerVisionImageUri));

Analyze Image

CustomHttpClient customHttpClient = new CustomHttpClient(new CustomHttpClientHandler(null));
AzureComputerVisionService azureComputerVisionService =
   new AzureComputerVisionService(null, this.AzureComputerVisionConfiguration,
   customHttpClient);
var allVisualFeatures = Enum.GetValues(typeof(VisualFeature)).Cast<VisualFeature>().ToList();
var allDetails = Enum.GetValues(typeof(Details)).Cast<Details>().ToList();
var result = await azureComputerVisionService.AnalyzeImageAsync(new Uri(this.TestComputerVisionImageUri),
allVisualFeatures, allDetails);

Read (For Text-heavy images)

CustomHttpClient customHttpClient = new CustomHttpClient(new CustomHttpClientHandler(null));
AzureComputerVisionService azureComputerVisionService =
   new AzureComputerVisionService(null, this.AzureComputerVisionConfiguration,
   customHttpClient);
var result = 
await azureComputerVisionService.ReadAsync(
   new Uri(ImageWithTextUrl));
var simpleRebuiltText =
   String.Join(" ", result.readResults.SelectMany(p => p.lines).Select(p => p.text));

Detect Text (OCR)

CustomHttpClient customHttpClient = new CustomHttpClient(new CustomHttpClientHandler(null));
AzureComputerVisionService azureComputerVisionService =
   new AzureComputerVisionService(null, this.AzureComputerVisionConfiguration,
   customHttpClient);
var result = 
await azureComputerVisionService.DetectTextAsync(
   new Uri(ImageWithTextUrl), 
   language: DetectImageLanguage.Spanish);
