MS Vision OCR low recognition

Question

Hi we try to read some text from screenshots,
but I recognize that the /vision/v3.2/ocr API has some issues recognizing text at all.
Is there an option to improve the API?

The following was not even in the result set:

And here it cannot identify the rn and reads m

@Grossmann, Tobias I would recommend to use the READ API which has a better accuracy than OCR and it is also asynchronous. You can use both handwritten and printed text to recognize the characters and set the language too in the request. For example, for the same images the response is very accurate. With a slightly better quality image I think you should see good results.
