摘要:

基于视频的计算机视觉应用通常需要在其第一步中检测移动对象。然后应用背景减法以分离背景和前景。背景减除是计算机视觉中研究最多的领域之一,发表的论文也很多。其中大多数涉及数学和机器学习模型的应用,以更好地应对视频中遇到的挑战。然而,最终的目标是研究中开发的背景减除方法可以用于交通监控等实际应用。但看看文献,我们可以注意到,在实际应用中使用的当前方法与基础研究中使用的当前方法之间往往存在差距。此外,在大规模数据集中评估的视频并不详尽,因为它们只涵盖了实际应用中遇到的全部挑战的一部分。在这种情况下,我们试图提供尽可能详尽的调查,在实际应用中,使用背景减法,以确定在实践中遇到的真正挑战,目前使用的背景模型,并提供未来的方向。因此,在相机,前景物体和环境方面的挑战进行了研究。此外,我们确定的背景模型,有效地用于这些应用程序中,以找到潜在的可用的最近的背景模型的鲁棒性,时间和内存的要求。

英文摘要:

Computer vision applications based on videos often require the detection of moving objects in their first step. Background subtraction is then applied in order to separate the background and the foreground. In literature, background subtraction is surely among the most investigated field in computer vision providing a big amount of publications. Most of them concern the application of mathematical and machine learning models to be more robust to the challenges met in videos. However, the ultimate goal is that the background subtraction methods developed in research could be employed in real applications like traffic surveillance. But looking at the literature, we can remark that there is often a gap between the current methods used in real applications and the current methods in fundamental research. In addition, the videos evaluated in large-scale datasets are not exhaustive in the way that they only covered a part of the complete spectrum of the challenges met in real applications. In this context, we attempt to provide the most exhaustive survey as possible on real applications that used background subtraction in order to identify the real challenges met in practice, the current used background models and to provide future directions. Thus, challenges are investigated in terms of camera, foreground objects and environments. In addition, we identify the background models that are effectively used in these applications in order to find potential usable recent background models in terms of robustness, time and memory requirements.
