Quick-Start

Using the sample below, we are going to illustrate how to extract the data that we want using the SDK.

Sample Code

#
# Install the Ruby client library by running:
# gem install mindee
#

require 'mindee'

# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')

# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')

# Parse the file
result = mindee_client.parse(
  input_source,
  Mindee::Product::DriverLicense::DriverLicenseV1
)

# Print a full summary of the parsed data in RST format
puts result.document

# Print the document-level parsed data
# puts result.document.inference.prediction

Sample Output (rST)

Standard Fields

These fields are generic and used in several products.

Basic Field

Each prediction object contains a set of fields that inherit from the generic Field class. A typical Field object will have the following attributes:

• value (String, Float, Integer, bool): corresponds to the field value. Can be nil if no value was extracted.

• confidence (Float, nil): the confidence score of the field prediction.

• bounding_box (Mindee::Geometry::Quadrilateral, nil): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.

• polygon (Mindee::Geometry::Polygon, nil): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.

• page_id (Integer, nil): the ID of the page, always nil when at document-level.

• reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

Aside from the previous attributes, all basic fields have access to a to_s method that can be used to print their value as a string.

Date Field

Aside from the basic Field attributes, the date field DateField also implements the following:

• date_object (Date): an accessible representation of the value as a JavaScript object.

String Field

The text field StringField only has one constraint: it's value is a String (or nil).
