RecognizeText(Printed) is not recognizing the pound symbol (£)
I have many cases of pictures of texts where one can find a pound sign (£) but the sign is NEVER correctly recognized by Azure Cognitive Services RecognizeText API, as far as I tested. Other symbols, like the dollar sign ($) for example, are identified without problems.
I made tests with print screens of texts containing £, since these should be easy for the OCR tool to convert, and again the pound sign is not correctly identified (it becomes an f, a 2, a 1, a $ etc).
I am suspecting that the pound sign is not included in the…

Response should contain column and row indices
Why should I have to calculate row and column indices? You're processing this data and know those numbers exactly. This data is far more valuable (at least to me) than your IList<int> of 1 -> n integers (bounding boxes) - that itself could use some reorganization. I'm testing out the big 3 OCR engines - Amazon, Google and Azure - Azure so far has the best scan results, but the poorest return object IMO.

The PDF coordinate system needs some work
The Read api (https://westus.dev.cognitive.microsoft.com/docs/services/5adf991815e1060e6355ad44/operations/2afb498089f74080d7ef85eb) does not handle PDF word coordinates correctly.
Did not see a way to report the bug on the API page, so I am reporting it here.
I am sending it a 8.5x11 page and getting coordinates in inches that are outside the box.
The width is marked as 10.9833 and height as 8.4567, however it is getting words outside that box:
12.3419
0.4349
13.2572
0.4294
13.2715
0.501
12.3562
0.5065When I print the coordinates to the page some documents are spot on the the x coordinate, but roughly half as far down the page…

Recognize Vancouver Olympic Torch in photo
Photo of landmark in Vancouver, Canada is incorrectly identified as "a plane parked on the side of the road" - it should at least be identified as a monument or sculpture.

Please provide the taxonomy for tagging and taxonomy used for object detection in the documentation.
Please provide the taxonomy for tagging and taxonomy used for object detection in the documentation.
It would fine if it is not an exhaustive list. This taxonomy would be more helpful to users to set predefined conditions for objects or tags.

Generate Human friendly operationId in swagger
Almost all tools that can generate API Client out of Swagger API defenition, will use OperationId to generate method name in a client. In your swagger API, OperationIds looks like "56f91f2e778daf14a499e1fa", and in C# it will produce method name public System.Threading.Tasks.Task 56f91f2e778daf14a499e1faAsync();
It's extremely hard to recognize what method doing, based on this operationIDPlease, modify operationIds in a swagger documentation https://westus.dev.cognitive.microsoft.com/docs/services/5adf991815e1060e6355ad44/export?DocumentFormat=Swagger&ApiName=Computer%20Vision%20API%20-%20v2.0 to make it human and code generator tools friendly.
P.S. I got this swagger file from https://westus.dev.cognitive.microsoft.com/docs/services/5adf991815e1060e6355ad44/operations/587f2c6a154055056008f200

The overview of a Computer Vision resource in the Azure portal still gives api.cognitive.microsoft.com/vision/v1.0 as the endpoint
It should say v2.0 instead
2 votesHello,
It looks like we support both endpoints. Can you please let me know where you are seeing this issue?
Thanks,

How far has the API gone with trying to detect people from the back view?
Can the API detect humans even from a back view. It might not be very accurate just like humans but after you have lived with someone else for a long time there is a high chance that you can guess who they are even from a back view. Therefore was wondering if the computer detected multiple images of people even from back view whether it would be able to guess.
