Web Job that gets data from Twitter, runs it through Azure.

Uses Node.js, gets tweets from API searching on hashtag. Gets all photos, creates base64 representation of that image, uses Vision API, added to CosmoDB.

How good is the confidence measure based on these categories? We can then publish it to the web in an interactive report.

You can even get full details about every landmark in the face, like where the pupils are. It can even be trained to recognize specific individuals.
