Multi Receipts Detector

The .NET SDK supports the Mindee V1 Multi Receipts Detector API.

Product Specifications

Specification	Details
Endpoint Name	multi_receipts_detector
Recommended Version	v1.1
Supports Polling/Webhooks	❌ No
Support Synchronous HTTP Calls	✔️ Yes
Geography	🌐 Global

Quick-Start

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

Sample Code

using Mindee;
using Mindee.Input;
using Mindee.Product.MultiReceiptsDetector;

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 as a path string
// Other input types can be used, as mentioned in the docs
var inputSource = new LocalInputSource(filePath);

// Call the API and parse the input
var response = await mindeeClient
    .ParseAsync<MultiReceiptsDetectorV1>(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());

Sample Output (rST)

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 (BoundingBox): 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 (int?): the ID of the page, always null when at document-level.

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.

PositionField

The position field PositionField implements:

• BoundingBox (BoundingBox): 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.

• Rectangle (Polygon): a Polygon with four points that may be oriented (even beyond canvas).

• Quadrangle (Quadrangle): a free polygon made up of four points.

Attributes

The following fields are extracted for Multi Receipts Detector V1:

List of Receipts

Receipts: Positions of the receipts on the document.

foreach (var ReceiptsElem in result.Document.Inference.Prediction.Receipts)
{
    System.Console.WriteLine(ReceiptsElem.Polygon);
    System.Console.WriteLine(ReceiptsElem.Quadrangle);
    System.Console.WriteLine(ReceiptsElem.Rectangle);
    System.Console.WriteLine(ReceiptsElem.BoundingBox);
}
