Are you looking at me? AI in Azure

Microsoft gives you a 12 month Azure free trial and so I thought I would have a play with some of their Cognitive Services API’s. Is the AI in Azure as good as it makes out to be? I setup both the Face and Computer Vision Tools. The Face tool has over 1 Million people matched and has the ability to recognize gender, age, and emotion, this gave me an idea to look for celeb photos on Twitter with hashtag #breakingnews to see how accurate it was at identifying celebs and how well it gauged their emotions.


Setting up the services was done via the cognitive services area of Azure. You are able to search the marketplace for the tool required and in this case I searched and created both Face and Computer Vision. The wizard for each was pretty straighforward. Create a resource group, choose a region, create a unique name for your instance (which will be included in your HTTP API Url) and the pricing tier of which there is a free one.

Very quickly your API is up and running and you are presented with a quick start guide with C# and Python examples. I took my idea to PowerAutomate and grabbed a copy of my EndPoint URL and one of the access keys.


So, I chose to limit the trigger of the automate by using a trigger condition where the MediaUrls entity was not empty, hopefully ensuring that any tweet retrieved by this trigger would be limited to those with a photo included.

My flow, triggered by hashtag #breakingnews where the following trigger condition was met

I also used two arrays to store people data from the massive body of data retrieved from the API calls as well as an Array to format data for a HTML table to summarize the age/gender and emotion data for the people found by the Face calls.

Computer Vision API HTTP POST

After the Computer Vision API had been called on the MediaUrls (of which I limited it to the first element of the MediaUrls object), I then ensured that the body for celebrities and captions were not empty using a condition:



If both conditions were met, I then I run the Face API to detect the Gender, Age and Emotion and output these to my earlier Array.


In my first attempt I emailed myself the summary of data captured, but after seeing some of the results I have begun to retweet the image with the data obtained from both API’s.

The above photo was taken in 2019 when Bill was 63, so he will be pleased to see the AI thinks he looks a year younger.
