English(EN) CodecMotion-OAD: Efficient Online Action Detection with Compressed-Domain Motion

新系统使用编解码器运动矢量进行快速在线动作检测

研究人员开发了CodecMotion-OAD,一种用于视频在线动作检测的新颖系统,该系统利用编解码器运动矢量(MVs)代替传统的光流。这种方法通过利用视频解码过程中可用的MVs,大大降低了计算负担,无需单独进行密集的光流计算。虽然在THUMOS'14基准测试上的性能略低于基于光流的方法,但CodecMotion-OAD提供了显著的速度提升,使其成为实时视频分析的更有效解决方案。 AI

影响 通过减少处理时间,为实时视频分析提供了一种计算效率更高的方法。

    CodecMotion-OAD:高效的压缩域运动在线动作检测

    arXiv:2610.26915v1 Announce Type: new Abstract: Online action detection (OAD) identifies ongoing actions in streaming videos. Many existing OAD systems combine RGB appearance with optical flow, but dense-flow extraction remains a major computational bottleneck. Codec motion vecto…
