#AZURE – #VisionAPI and optical character recognition #OCR


The API VisionAPI in Project Oxford also gives us the ability to perform optical character recognition in an image. What we usually known as OCR.

The result of the OCR process, shows us information with

  • the language of the detected language
  • the area where the text has been detected
  • the angle of the text
  • a collection of lines within each area of detected text
  • a collection of words per line

So a McDonalds sign returns the following information


Language: en
Orientation: Up
Text Angle: 5.89999999999997

Left 75, Top 74,
Height 132, Width 210

please do not
eat the
all white meat chicken

The About Windows form returns


Language: en
Orientation: Up
Text Angle: 0

Left 9, Top 11,
Height 311, Width 402
