Introduction to OCR
Optical Character Recognition (OCR) recognizes and converts characters and digits in an image into editable text.
OCR provides the text recognition capability through open application programming interfaces (APIs). To call APIs and process the recognition result returned in JSON format, you need to have basic knowledge of programming.
Use either of the following methods to call OCR APIs:
- Visualization tool (such as curl or Postman)
Apply to developers who are familiar with coding, HTTP requests, and API calling. For details, see Using Postman to Call OCR.
- Software development kit (SDK)
Apply to developers who are familiar with coding and allow you to use SDKs for Java, Python, iOS, Android, and Node.js for quick integration. For details, see Using SDK to Call OCR.
