Passport - India sample

Quick-Start

<?php

use Mindee\Client;
use Mindee\Product\Ind\IndianPassport\IndianPassportV1;

// Init a new client
$mindeeClient = new Client("my-api-key");

// Load a file from disk
$inputSource = $mindeeClient->sourceFromPath("/path/to/the/file.ext");

// Parse the file asynchronously
$apiResponse = $mindeeClient->enqueueAndParse(IndianPassportV1::class, $inputSource);

echo $apiResponse->document;

Output (RST):

Field Types

Standard Fields

These fields are generic and used in several products.

BaseField

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

  • value (float|string): corresponds to the field value. Can be null if no value was extracted.
  • confidence (float): the confidence score of the field prediction.
  • boundingBox ([Point, Point, Point, Point]): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
  • polygon (Point[]): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.
  • pageId (integer): the ID of the page, always null when at document-level.
  • reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

Note: A Point simply refers to a list of two numbers ([float, float]).

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

ClassificationField

The classification field ClassificationField does not implement all the basic BaseField attributes. It only implements value, confidence and pageId.

Note: a classification field's value is always a string`.

DateField

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

  • dateObject (date): an accessible representation of the value as a php object. Can be null.

StringField

The text field StringField implements the following:

  • value (string): represents the value of the field as a string.
  • rawValue (string): the value of the string as it appears on the document.
