          Summary

          OCR (Optical character recognition) is a technology that finds the position of a letter in an image (photo) and automatically identifies the letter. CLOVA OCR has its own character area detection and recognition technology to understand various types of characters.
          It also makes it easy to create templates, specify the areas you want, and quickly extract only the text you need.
          CLOVA OCR API is an API that provides character recognition based on the template set by CLOVA OCR Builder. It receives the language and image data to be used for recognition and returns the recognition result as text.
