Using face API with an already opened cv2 image

[shub-garg]

Please provide us with the following information:

How do I use azure face API with an already opened cv2 image without saving it again locally or on the web?
I tried looking for it in the documentations, but couldn't find a solution.
As far as I know and could find, there are only two ways of reading an image:

1. detect_with_url : Needs an URL to read the image.
2. detect_with_stream: Needs an image path to read the image.

This issue is for a: (mark with an x)

- [ ] bug report -> please search issues before submitting
- [ ] feature request
- [x] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Expected/desired behavior

The face API should have a function or work-around to use an already opened image without having to save it.

OS and Version?

Windows 10 and Raspberry Pi
