The following images show the prediction outputs of our model with the name of an object and its probability. You need to have your AWS DeepLens located in front of a rectangular-shaped whiteboard or a piece of white paper to ensure that the edges are visible in the frame.


In this tutorial, you learned about the preprocessing algorithm to isolate a drawing area and how to deploy a pre-trained model onto AWS DeepLens to recognize sketches. Next, you learned how to send results from AWS IoT to Kinesis Data Streams. Finally, you learned how to create a custom Alexa skill with Lambda to retrieve the detected objects in the data stream and return the results to players via Alexa.

Don’t forget to turn off your Kinesis Stream and delete AWS resources created as part of this tutorial to avoid being charged.
