Detect faces with the Azure AI Vision service

4 minutes

To detect and analyze faces with the Azure AI Vision service, call the Analyze Image function (SDK or equivalent REST method), specifying People as one of the visual features to be returned.

In images that contain one or more people, the response includes details of their location in the image and the attributes of the detected person, like this:

{ 
  "modelVersion": "2023-10-01",
  "metadata": {
    "width": 400,
    "height": 600
  },
  "peopleResult": {
    "values": [
      {
        "boundingBox": {
          "x": 0,
          "y": 56,
          "w": 101,
          "h": 189
        },
        "confidence": 0.9474349617958069
      },
      {
        "boundingBox": {
          "x": 402,
          "y": 96,
          "w": 124,

        },
