US US Mail OCR .NET
The .NET OCR SDK supports the US Mail API.
The sample below can be used for testing purposes.
Quick-Start
using Mindee;
using Mindee.Input;
using Mindee.Product.Us.UsMail;
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 product asynchronously with auto-polling
var response = await mindeeClient
.EnqueueAndParseAsync<UsMailV3>(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());
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 (
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
extendsList<Point>
) of a polygon containing the field in the image. - PageId (
int?
): the ID of the page, alwaysnull
when at document-level.
Note: A
Point
simply refers to a List ofdouble
.
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.
BooleanField
The boolean field BooleanField
extends BaseField, but also implements:
- Value (
bool?
): corresponds to the value of the field.
Specific Fields
Fields which are specific to this product; they are not used in any other product.
Recipient Addresses Field
The addresses of the recipients.
A UsMailV3RecipientAddress
implements the following attributes:
- City (
string
): The city of the recipient's address. - Complete (
string
): The complete address of the recipient. - IsAddressChange (
bool?
): Indicates if the recipient's address is a change of address. - PostalCode (
string
): The postal code of the recipient's address. - PrivateMailboxNumber (
string
): The private mailbox number of the recipient's address. - State (
string
): Second part of the ISO 3166-2 code, consisting of two letters indicating the US State. - Street (
string
): The street of the recipient's address. - Unit (
string
): The unit number of the recipient's address.
Fields which are specific to this product; they are not used in any other product.
Sender Address Field
The address of the sender.
A UsMailV3SenderAddress
implements the following attributes:
- City (
string
): The city of the sender's address. - Complete (
string
): The complete address of the sender. - PostalCode (
string
): The postal code of the sender's address. - State (
string
): Second part of the ISO 3166-2 code, consisting of two letters indicating the US State. - Street (
string
): The street of the sender's address.
Attributes
The following fields are extracted for US Mail V3:
Return to Sender
IsReturnToSender: Whether the mailing is marked as return to sender.
System.Console.WriteLine(result.Document.Inference.Prediction.IsReturnToSender.Value);
Recipient Addresses
RecipientAddresses(List<UsMailV3RecipientAddress>): The addresses of the recipients.
foreach (var RecipientAddressesElem in result.Document.Inference.Prediction.RecipientAddresses)
{
System.Console.WriteLine(RecipientAddressesElem.Value);
}
Recipient Names
RecipientNames: The names of the recipients.
foreach (var RecipientNamesElem in result.Document.Inference.Prediction.RecipientNames)
{
System.Console.WriteLine(RecipientNamesElem.Value);
}
Sender Address
SenderAddress(UsMailV3SenderAddress): The address of the sender.
System.Console.WriteLine(result.Document.Inference.Prediction.SenderAddress.Value);
Sender Name
SenderName: The name of the sender.
System.Console.WriteLine(result.Document.Inference.Prediction.SenderName.Value);
