论文摘要

随着计算机视觉技术在智能运输应用中变得越来越成熟,现在该询问它们在大规模和实时部署方面的效率和可扩展性。这些技术包括车辆重新识别,这是城市规模的车辆分析系统中的关键要素之一。许多用于车辆重新ID的最先进的解决方案主要集中在提高现有重新ID基准的准确性,并且通常忽略了计算复杂性。为了平衡准确性和计算效率的需求,在这项工作中,我们提出了一种简单而有效的混合解决方案,该解决方案是由自我监督训练赋予的能力,该解决方案仅在推理期间仅使用一个网络,并且没有复杂的和计算的附加模块,通常在目前的方法中经常看到。通过广泛的实验,我们显示了我们的方法,称为自我监督和增强的车辆重新识别(SSBVER),就准确性而言与最先进的替代方案相提并论,而没有在部署期间引入任何其他开销。此外,我们表明我们的方法概括为不同的骨干体系结构,从而有助于各种资源限制,并始终如一地提高准确性的提升。

As Computer Vision technologies become more mature for intelligent transportation applications, it is time to ask how efficient and scalable they are for large-scale and real-time deployment. Among these technologies is Vehicle Re-Identification which is one of the key elements in city-scale vehicle analytics systems. Many state-of-the-art solutions for vehicle re-id mostly focus on improving the accuracy on existing re-id benchmarks and often ignore computational complexity. To balance the demands of accuracy and computational efficiency, in this work we propose a simple yet effective hybrid solution empowered by self-supervised training which only uses a single network during inference time and is free of intricate and computation-demanding add-on modules often seen in state-of-the-art approaches. Through extensive experiments, we show our approach, termed Self-Supervised and Boosted VEhicle Re-Identification (SSBVER), is on par with state-of-the-art alternatives in terms of accuracy without introducing any additional overhead during deployment. Additionally we show that our approach, generalizes to different backbone architectures which facilitates various resource constraints and consistently results in a significant accuracy boost.
