quickdrawpaloja

Quickdrawpaloja is an open-source library and accompanying dataset designed for rapid sketch input and recognition in web and mobile applications. The library provides a canvas component with responsive rendering, stroke normalization, and a simple recognition interface for building drawing-centric user interfaces. The project targets educational tools, sketch-based search, and rapid prototyping of drawing apps. The name combines QuickDraw, referencing fast sketching, with Paloja, a fictional dataset used to illustrate category exemplars within the project.

It exposes a compact API for capturing stroke data, smoothing trajectories, and exporting sketches as vectors or bitmaps. It supports multi-touch input, basic pen pressure and tilt on compatible devices, and offline operation. The Paloja dataset provides curated example sketches across several categories to aid testing and demonstration.

Development is community-driven, with periodic updates aimed at performance, accessibility, and cross-platform compatibility. The project emphasizes portability and minimal dependencies, enabling deployment in lightweight web apps and offline environments.

Common use cases include educational activities, quick ideation in product design, and research studies on gesture input and recognition. The project also serves as a reference implementation for exploring drawing-based interfaces.
