摘要

在本文中，我们提出了用于隐私保护的轻量级加扰JPEG XS编码。提出的方法作为加密-压缩(EtC)系统运行。它允许使用EtC方案，同时保持与JPEG XS的兼容性。输入图像被打乱并馈送到JPEG XS。尽管有加扰，但速率失真性能仅略有下降。该方法在不加扰的情况下，具有与JPEG XS几乎相同的率失真性能。通过对8K超高清图像的仿真验证了其性能。

Lightweight Scrambled JPEG XS Coding for Privacy Protection

In this paper, we propose lightweight scrambled JPEG XS coding for privacy protection. The proposed method operates as an Encryption-then-Compression (EtC) system. It enables the EtC scheme to be used while maintaining compatibility with JPEG XS. Input images are scrambled and fed to JPEG XS. Despite the scrambling, the rate-distortion performance is only slightly degraded. The proposed method provides almost the same rate-distortion performance as that of JPEG XS without scrambling. We demonstrate its performance via simulation for 8K ultra-high-definition images.
