US US Mail OCR Python
The Python OCR SDK supports the US Mail API.
The sample below can be used for testing purposes.
Quick-Start
#
# Install the Python client library by running:
# pip install mindee
#
from mindee import Client, product, AsyncPredictResponse
# Init a new client
mindee_client = Client(api_key="my-api-key")
# Load a file from disk
input_doc = mindee_client.source_from_path("/path/to/the/file.ext")
# Load a file from disk and enqueue it.
result: AsyncPredictResponse = mindee_client.enqueue_and_parse(
product.us.UsMailV3,
input_doc,
)
# Print a brief summary of the parsed data
print(result.document)
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:
- value (
Union[float, str]
): corresponds to the field value. Can beNone
if no value was extracted. - confidence (
float
): the confidence score of the field prediction. - bounding_box (
[Point, Point, Point, Point]
): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document. - polygon (
List[Point]
): contains the relative vertices coordinates (Point
) of a polygon containing the field in the image. - page_id (
int
): the ID of the page, alwaysNone
when at document-level. - reconstructed (
bool
): indicates whether an object was reconstructed (not extracted as the API gave it).
Note: A
Point
simply refers to a List of two numbers ([float, float]
).
Aside from the previous attributes, all basic fields have access to a custom __str__
method that can be used to print their value as a string.
StringField
The text field StringField
only has one constraint: its value is an Optional[str]
.
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 (
str
): The city of the recipient's address. - complete (
str
): The complete address of the recipient. - is_address_change (
bool
): Indicates if the recipient's address is a change of address. - postal_code (
str
): The postal code of the recipient's address. - private_mailbox_number (
str
): The private mailbox number of the recipient's address. - state (
str
): Second part of the ISO 3166-2 code, consisting of two letters indicating the US State. - street (
str
): The street of the recipient's address. - unit (
str
): 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 (
str
): The city of the sender's address. - complete (
str
): The complete address of the sender. - postal_code (
str
): The postal code of the sender's address. - state (
str
): Second part of the ISO 3166-2 code, consisting of two letters indicating the US State. - street (
str
): The street of the sender's address.
Attributes
The following fields are extracted for US Mail V3:
Return to Sender
is_return_to_sender (BooleanField): Whether the mailing is marked as return to sender.
print(result.document.inference.prediction.is_return_to_sender.value)
Recipient Addresses
recipient_addresses (List[UsMailV3RecipientAddress]): The addresses of the recipients.
for recipient_addresses_elem in result.document.inference.prediction.recipient_addresses:
print(recipient_addresses_elem.value)
Recipient Names
recipient_names (List[StringField]): The names of the recipients.
for recipient_names_elem in result.document.inference.prediction.recipient_names:
print(recipient_names_elem.value)
Sender Address
sender_address (UsMailV3SenderAddress): The address of the sender.
print(result.document.inference.prediction.sender_address.value)
Sender Name
sender_name (StringField): The name of the sender.
print(result.document.inference.prediction.sender_name.value)
