摘要:

语义背景减除(Semantic background subtraction,SBS)已被证明可以通过将大多数背景减除算法与来自语义分割网络的语义信息相结合来提升其性能。然而,SBS需要所有帧的高质量语义分割掩码,而这些掩码的计算速度很慢。此外,大多数最先进的背景减除算法并非实时算法,这使其不适用于真实世界应用。本文提出一种名为实时语义背景减除(Real-Time Semantic Background Subtraction,记为RT-SBS)的新型背景减除算法,它将SBS扩展到受实时约束的应用,同时保持相近性能。RT-SBS有效地将实时背景减除算法与高质量语义信息相结合;这些语义信息可以以较慢的速度、按每个像素独立提供。我们表明,与ViBe结合的RT-SBS为实时背景减除算法确立了新的最先进水平,甚至可与非实时的最先进算法相竞争。请注意,我们在https://github.com/cioppaanthony/rt-sbs提供RT-SBS的Python CPU和GPU实现。

英文摘要:

Semantic background subtraction SBS has been shown to improve the performance of most background subtraction algorithms by combining them with semantic information, derived from a semantic segmentation network. However, SBS requires high-quality semantic segmentation masks for all frames, which are slow to compute. In addition, most state-of-the-art background subtraction algorithms are not real-time, which makes them unsuitable for real-world applications. In this paper, we present a novel background subtraction algorithm called Real-Time Semantic Background Subtraction (denoted RT-SBS) which extends SBS for real-time constrained applications while keeping similar performances. RT-SBS effectively combines a real-time background subtraction algorithm with high-quality semantic information which can be provided at a slower pace, independently for each pixel. We show that RT-SBS coupled with ViBe sets a new state of the art for real-time background subtraction algorithms and even competes with the non real-time state-of-the-art ones. Note that we provide python CPU and GPU implementations of RT-SBS at https://github.com/cioppaanthony/rt-sbs.
