新型可变形2D码，支持任意风格化且抗形变能力强。
Claycode: Stylable and Deformable 2D Scannable Codes
- 用树状结构编码，以颜色区域嵌套方式生成
- 在严重变形下仍能准确解码，优于传统二维码
- 适合创意设计与动态场景应用
本文提出Claycode，一种新型2D可扫描码，支持广泛风格化与形变适应。不同于基于矩阵的传统码（如二维码），Claycode将信息编码为树形拓扑结构，并将其可视化为在目标多边形边界内嵌套的颜色区域。解码过程可在摄像头实时流中完成。我们展示了完整的端到端流程，证明Claycode在保持功能性的同时可实现高度风格化。实验证明，其对严重形变具有强鲁棒性，在传统码通常失效的场景中表现更优。
原文摘要 · Abstract (English)
This paper introduces Claycode, a novel 2D scannable code designed for extensive stylization and deformation. Unlike traditional matrix-based codes (e.g., QR codes), Claycodes encode their message in a tree structure. During the encoding process, bits are mapped into a topology tree, which is then depicted as a nesting of color regions drawn within the boundaries of a target polygon shape. When decoding, Claycodes are extracted and interpreted in real-time from a camera stream. We detail the end-to-end pipeline and show that Claycodes allow for extensive stylization without compromising their functionality. We then empirically demonstrate Claycode's high tolerance to heavy deformations, outperforming traditional 2D scannable codes in scenarios where they typically fail.
