Draw This: Neural Network Turns Polaroid Pics Into Doodles #piday #raspberrypi @Raspberry_Pi

Dan Macanish shares this fun project over on his blog!

Draw This is a polaroid camera that draws cartoons.

The polaroid camera is a classic that still delights today. There is something eternally amusing about a physical, unique image, that is uniquely different to digital. Playing with neural networks for object recognition one day, I wondered if I could take the concept of a polaroid one step further, and ask the camera to re-interpret the image, printing out a cartoon instead of a faithful photograph.

The camera is a mash up of a neural network for object recognition, the google quickdraw dataset, a thermal printer, and a raspberry pi. Initially, I began with some experiments on my laptop. I set up an image processing pipeline in python to take pre-captured images and recognise the objects in them, using pre-trained models from google. At the same time, I explored the quickdraw dataset, and mapped the categories available in the dataset with the categories recognisable by the image processor. After writing some code to patch the two together, wrapping the lot in a docker image, and cobbling together some electronics, interspersed with some hair pulling moments of frustration, the camera was ready.
