This video tutorial walks you through the complete end-to-end flow on how one can generate a thumbnail from an image using Azure Cognitive Services – Computer Vision API. The workflow starts by adding an image into Azure Storage, passing it to Computer Vision, and storing the generated thumbnail back to Azure Storage and all this is achieved without writing even a single line of code. 

On the technology front, it uses Azure Computer Vision API, Azure Blob Container, and Logic Apps.
