AI总结:

本文针对可扩展人机编码中基础层效率问题,分析现有最先进图像编解码器的基础层编码效率,并提出改进方法,在目标检测和实例分割任务上实现 BD-Rate 20-40% 的增益。

摘要:

可扩展人机编码的一个基本前提是,基础层旨在用于自动化机器分析,因此与供人类观看的相同内容相比,其可压缩性更高。此类编码的用例包括视频监控和交通监控,其中绝大多数内容永远不会被人类查看。因此,基础层效率至关重要,因为系统最常以基础层速率运行。在本文中,我们分析了一种最先进的可扩展人机图像编解码器中基础层的编码效率,并表明其效率可以得到提升。特别是,我们证明了与目前在目标检测和实例分割上的最佳结果相比,BD-Rate 可节省 20-40%。

英文摘要:

A basic premise in scalable human-machine coding is that the base layer is intended for automated machine analysis and is therefore more compressible than the same content would be for human viewing. Use cases for such coding include video surveillance and traffic monitoring, where the majority of the content will never be seen by humans. Therefore, base layer efficiency is of paramount importance because the system would most frequently operate at the base-layer rate. In this paper, we analyze the coding efficiency of the base layer in a state-of-the-art scalable human-machine image codec, and show that it can be improved. In particular, we demonstrate that gains of 20-40% in BD-Rate compared to the currently best results on object detection and instance segmentation are possible.
