Cannot detect number with OCR

Question

I try to get the number and it's position in the image using Azure Cognitive Services OCR but it cannot detect any number in the image. Here is the Image that I used. (I'm using a sample code from https://docs.microsoft.com/en-us/azure/cognitive-services/computer-vision/quickstarts/csharp )

Thank you, Art

That is a known problem for Microsoft and Goolge cloud OCR - they fail on isolated characters while working well on longer lines of text. You may consider alternative cloud OCR services, for example this one: http://ocrsdk.com It works perfectly on image you provided.
