Introduction

SigNATURE recognition is a technology or process that involves the automatic identification and interpretation of structured information from various types of documents or forms. It typically utilizes computer software and often incorporates techniques like Optical Character Recognition (OCR) and pattern recognition to analyze and identify from printed or digital documents.

• Document Types: Signature recognition can be applied to a wide range of documents, including printed forms, invoices, surveys, questionnaires, application forms, contracts, identification documents, and more.

• Data Extraction: The primary goal of signature recognition is to identify signature location from these documents.

• Automation: Signature recognition is often used to automate processing. Once signatures are identified, it can be automatically integrated into databases, information systems, or business processes, reducing the need for manual procesing and minimizing errors.

API Endpoints

/signature

Description

Return metadata formatted as JSON. Each unit will include:

• Type: “SIGNATURE”
• Confidence = level of confidence from 0 to 100
• BoundingBox
  • Height = height of the bounding box as a ratio of the overall document page dimension
  • Left = X-coordinate, ratios of the overall document page size
  • Top = Y-coordinate, ratios of the overall document page size
  • Width = width of the bounding box as a ratio of the overall document page dimension

For example, if the input image is 700 x 200 pixels, and the top-left coordinate of the bounding box is 350 x 50 pixels, the API returns a left value of 0.5 (350/700) and a top value of 0.25 (50/200). The upper-left corner of the image is the origin (0,0).

Request

The body of the request contains the binary data of the image to be processed. The binary data can be represented as:

• Straight binary data
• Data Url Schema (https://datatracker.ietf.org/doc/html/rfc2397)
• Mulipart Form Data - first file is used (https://datatracker.ietf.org/doc/html/rfc1867)
