The Java OCR SDK supports the Invoice Splitter API.

Using this sample, we are going to illustrate how to detect the pages of multiple invoices within the same document.

Quick-Start

⚠️ Important: This API only works asynchronously, which means that documents have to be sent and retrieved in a specific way:

import com.mindee.MindeeClient;
import com.mindee.input.LocalInputSource;
import com.mindee.parsing.common.AsyncPredictResponse;
import com.mindee.parsing.common.Job;
import com.mindee.parsing.common.Document;
import com.mindee.product.invoicesplitter.InvoiceSplitterV1;
import java.io.File;
import java.io.IOException;
import java.util.Optional;

public class SimpleMindeeClient {

  public static void main(String[] args) throws IOException, InterruptedException {
    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(new File(filePath));

    // Parse the file asynchronously
    AsyncPredictResponse<InvoiceSplitterV1> response = mindeeClient.enqueueAndParse(
      InvoiceSplitterV1.class,
      inputSource
    );

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

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

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

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

Field Types

Specific Fields

Page Indexes

List of page group indexes.

A PageIndexes implements the following attributes:

pageIndexes (List<Integer>): List of indexes of the pages of a single invoice.
confidence (Double): The confidence of the prediction.

Attributes

The following fields are extracted for Invoice Splitter V1:

Invoice Page Groups

invoicePageGroups (List<invoicePageGroups>): List of page indexes that belong to the same invoice in the PDF.

for (invoicePageGroupsElem : result.getDocument().getInference().getPrediction().getInvoicePageGroups())
{
  System.out.println(invoicePageGroupsElem);
}
