QuickDraw

Why we included this project

Sketch recognition is a good place to see computer vision work end to end, and this repo walks through it with one CNN. A trained model already sorts hand-drawn doodles into 20 everyday classes from Google's Quick, Draw! dataset, and the training scripts are included. Two runnable apps make the results tangible: one follows a blue, red, or green pen in front of your webcam while you draw in the air, the other lets you draw on a canvas. Changing the category list is just editing a constant in the config and downloading the matching npz files, so you can retrain on your own set of sketches without touching the rest of the pipeline. It feels more like a compact tutorial than a production service, which makes it a practical study project for anyone getting into sketch or gesture classification.
