标题： Revelio: A Real-World Screen-Camera Communication System with Visually Imperceptible Data Embedding

摘要： 我们提出“Revelio”，一个利用OKLAB颜色空间中时间闪烁融合的真实世界屏幕-相机通信系统。 通过空间自适应闪烁并在像素区域形状中编码信息， Revelio在保持对噪声、异步性和屏幕-相机信道失真的鲁棒性的同时，实现了视觉不可察觉的数据嵌入，确保标准智能手机相机能够可靠解码。 解码器由两级神经网络驱动，使用加权差分累加器进行精确的帧检测和符号识别。 初步实验表明 Revelio在互动电视中的有效性，为元信息传输提供了一种无干扰的方法。 显示英文摘要

摘要： We present `Revelio', a real-world screen-camera communication system leveraging temporal flicker fusion in the OKLAB color space. Using spatially-adaptive flickering and encoding information in pixel region shapes, Revelio achieves visually imperceptible data embedding while remaining robust against noise, asynchronicity, and distortions in screen-camera channels, ensuring reliable decoding by standard smartphone cameras. The decoder, driven by a two-stage neural network, uses a weighted differential accumulator for precise frame detection and symbol recognition. Initial experiments demonstrate Revelio's effectiveness in interactive television, offering an unobtrusive method for meta-information transmission.
