I have introduced some candidates for OCR in the previous posts such as C# – OCR library candidates and C# – An example of OCR web service. Last year Microsoft published his new project for machine learning. The project is called Project Oxford. This project provides us the APIs for computer vision, face, emotion, video, speech, speaker recognition… The project is really interesting, you can learn more about it from its homepage. In this small post, I would like to illustrate how we can make a call to OCR service. OCR ist just a part of Computer Vision APIs.
