The .NET 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

using Mindee;
using Mindee.Input;
using Mindee.Product.InvoiceSplitter;

string apiKey = "my-api-key";
string filePath = "/path/to/the/file.ext";

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

// load an input source
var inputSource = new LocalInputSource(filePath);

// call the product asynchronously with auto-polling
var response = await mindeeClient
    .EnqueueAndParseAsync<InvoiceSplitterV1>(inputSource);

// Print a summary of all the predictions
System.Console.WriteLine(response.Document.ToString());

// Print only the document-level predictions
// System.Console.WriteLine(response.Document.Inference.Prediction.ToString());

Output (RST):

Invoice Splitter V1 Page Group

List of page group indexes.

An InvoiceSplitterV1PageGroup implements the following attributes:

PageIndexes (int[]): 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

PageGroups (List<InvoiceSplitterV1PageGroup>): List of page indexes that belong to the same invoice in the PDF.

foreach (var InvoiceSplitterV1PageGroupElem in result.Document.Inference.Prediction.InvoiceSplitterV1PageGroup)
{
    System.Console.WriteLine(InvoiceSplitterV1PageGroupElem).Polygon;
}
