Local Setup

We are using Python3.

Install Watson Developer module pip3 install watson_developer_cloud

Execution

• Run the script using Python3
• You have 3 choices
  1. Visual Recognotion
  2. Text Recognition
  3. Facial Recognition

Visual Recognition

Visual Recognition understands the contents of an image

Output of analyzing above image will be

[{'class': 'subcompact car',
  'score': 0.948,
  'type_hierarchy': '/vehicle/subcompact car'},
 {'class': 'car', 'score': 0.974},
 {'class': 'vehicle', 'score': 0.974},
 {'class': 'compact car',
  'score': 0.53,
  'type_hierarchy': '/vehicle/compact car'},
 {'class': 'steel blue color', 'score': 0.894}]

Text Recognition

Text Recognition tries to read the text in a given image

Output of analyzing above image will be

hospital

Facial Recognition

Facial recognition tries to find human faces, approximate age, gender etc

Output of analyzing above image will be

Name : Barack Obama
Gender : MALE
Age : 55-64
