OCR using computer vision API for cropped images

I have an issue regarding results generated from azure

I have one image which I want to OCR. (See full.jpg). This works fine with this image and all data is extracted. But when I crop a certain portion of this image and pass this as a new image (See crop.jpg), the OCR fails. The same part of this image in full.jpg is extracted fine,


Assistance would be appreciated

I get similar results to you. I made my own crop of the image and using it will detect the word Quantity but not the numbers, but only if I set parameters to force the language to be English and set detectOrientation to false.

@arunprasathjp-2632 Improvements to the models to recognize single character images will be shipped in our future releases which should address this issue. We do not have an ETA for this release but we shall update the notes when we have more updates.
