IBM Watson Support

[28mm]

IBM Watson's Visual Recognition service has a free tier that supports < 250 requests / day. It does image classification and face detection, as well as supporting a category schema like Microsoft's. It appears to support celebrity detection via the same category system.

Example Image Classification:

{
 "custom_classes": 0,
  "images": [
    {
        "classifiers": [
            {
                "classes": [
                    {
                        "class": "banana",
                        "score": 0.81,
                        "type_hierarchy": "/fruit/banana"
                    },
                    {
                        "class": "fruit",
                        "score": 0.922
                    },
                    {
                        "class": "mango",
                        "score": 0.554,
                        "type_hierarchy": "/fruit/mango"
                    },
                    {
                        "class": "olive color"
                        "score": 0.951
                    },
                    {
                        "class": "olive green color"
                        "score": 0.747
                    }
                ],
                "classifier_id": "default",
                "name": "default"
            }
        ],
        "image": "fruitbowl.jpg"
    }
  ],
  "images_processed": 1
}

Example face and Identity detection:

{
  "images": [
    {
      "faces": [
        {
          "age": {
            "max": 54,
            "min": 45,
            "score": 0.364876
          },
          "face_location": {
            "height": 117,
            "left": 406,
            "top": 149,
            "width": 108
          },
          "gender": {
            "gender": "MALE",
            "score": 0.993307
          },
          "identity": {
            "name": "Barack Obama",
            "score": 0.982014
            "type_hierarchy": "/people/politicians/democrats/barack obama"
          }
        }
      ],
      "image": "prez.jpg"
    }
  ],
  "images_processed": 1
}

With the foregoing commits, the --labels and --faces features work with the watson provider. Still to do:

1. --celebrities: this should come for free with face detection as the identity field. Watson gives a canonical name for the detected celebrity, its confidence, and the celebrity's type hierarchy. Some thought required to handle this last piece, which is unavailable via Microsoft's celebrity detection feature.
2. Documentation updates: readme.md, .../examples
3. Custom classifiers. Watson supports custom classifiers, as does Clarifai. How should support for this look?

The daily transaction limit for Watson's free plan is set fairly low.

{
    "labels": {
        "status": "ERROR",
        "statusInfo": "daily-transaction-limit-exceeded"
    }
