Hi James -

I'm the Computer Vision PM for Cognitive Services, and can, hopefully, provide some clarity on the API performance and usage here. From your screenshot, it looks like you are using the Vision API intended for image tagging and captioning (/analyze operation of the API), not the one you need to use for OCR.

In order to evaluate handwriting recognition of the Computer Vision API (/recognizeText operation), go to https://azure.microsoft.com/en-us/services/cognitive-services/computer-vision/ and scroll down to another interactive demo called Preview: Read handwritten text from images. Using the screenshot above, the results you would get would be:
I believe it is the third demo on the page. Similarly, to recognize printed text, use the second demo on the page (called Read text in images).

Please don't hesitate to reach out if you have other questions.

I've been wanting to use the Cognitive API for our Tumblr site, OK2Talk.org but the accuracy of the Computer Vision API is significantly lower than I would like. When I compare the same images with Google's Vision API, their results are much closer to what images depict.

Here is a simple test I put through both API's.

Tell me this is apples and oranges please... I want to like Microsoft's Cognitive API, but can I rely on it at this point?
