The Java OCR SDK supports the Carte Vitale API.

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

Quick-Start

import com.mindee.MindeeClient;
import com.mindee.input.LocalInputSource;
import com.mindee.parsing.common.PredictResponse;
import com.mindee.product.fr.cartevitale.CarteVitaleV1;
import java.io.File;
import java.io.IOException;

public class SimpleMindeeClient {

  public static void main(String[] args) throws IOException {
    String apiKey = "my-api-key";
    String filePath = "/path/to/the/file.ext";

    // Init a new client
    MindeeClient mindeeClient = new MindeeClient(apiKey);

    // Load a file from disk
    LocalInputSource inputSource = new LocalInputSource(filePath);

    // Parse the file
    PredictResponse<CarteVitaleV1> response = mindeeClient.parse(
        CarteVitaleV1.class,
        inputSource
    );

    // Print a summary of the response
    System.out.println(response.toString());

    // Print a summary of the predictions
//  System.out.println(response.getDocument().toString());

    // Print the document-level predictions
//    System.out.println(response.getDocument().getInference().getPrediction().toString());

    // Print the page-level predictions
//    response.getDocument().getInference().getPages().forEach(
//        page -> System.out.println(page.toString())
//    );
  }

}

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:

confidence (Double): the confidence score of the field prediction.
boundingBox (Polygon): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
polygon (Polygon): contains the relative vertices coordinates (polygon extends List<Point>) of a polygon containing the field in the image.
pageId (Integer): the ID of the page, always null when at document-level.

Note: A Point simply refers to a List of Double.

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.

StringField

The text field StringField extends BaseField, but also implements:

value (String): corresponds to the field value.
rawValue (String): corresponds to the raw value as it appears on the document.

DateField

The date field DateField extends BaseField, but also implements:

value (LocalDate): an accessible representation of the value as a Java object. Can be null.

Attributes

The following fields are extracted for Carte Vitale V1:

Given Name(s)

givenNames: The given name(s) of the card holder.

for (givenNamesElem : result.getDocument().getInference().getPrediction().getGivenNames())
{
    System.out.println(givenNamesElem.value);
}

Issuance Date

issuanceDate: The date the card was issued.

System.out.println(result.getDocument().getInference().getPrediction().getIssuanceDate().value);

Social Security Number

socialSecurity: The Social Security Number (Numéro de Sécurité Sociale) of the card holder

System.out.println(result.getDocument().getInference().getPrediction().getSocialSecurity().value);

Surname

surname: The surname of the card holder.

System.out.println(result.getDocument().getInference().getPrediction().getSurname().value);
