English(EN) Spatial Artifact Coherence Determines Codec Robustness in Patch-Based rPPG

新指标预测视频压缩下rPPG算法性能

作者 PulseAugur 编辑部 · [1 个来源] · 2026-06-04 04:00

研究人员开发了一种名为空间伪影相干性（SAC）的新指标，用于预测远程光电容积脉搏波描记法（rPPG）算法在视频压缩下的性能。SAC通过视频块的协方差矩阵计算得出，能有效区分不同的编解码器家族及其对rPPG准确性的影响。研究发现，某些条件，如低到中度运动和特定的SAC值，是基于块的方法优于全局投影技术的必要条件，为在临床应用中选择鲁棒算法提供了指导。 AI

影响提供了一种在压缩视频条件下选择用于远程健康监测的鲁棒AI算法的方法。
