Within the field of computer vision, change detection algorithms aim at automatically
detecting significant changes occurring in a scene by analyzing the sequence of frames in a …

The extraction of moving objects from their background is a challenging task in visual
surveillance. As a single threshold often fails to resolve ambiguities and correctly segment …

In this paper a new color space, called the RGB color ratio space, is proposed and defined
according to a reference color such that an image can be transformed from a conventional …

Moving object detection has been widely used in diverse discipline such as intelligent
transportation systems, airport security systems, video monitoring systems, and so on. In this …

In dynamic object detection, it is challenging to construct an effective model to sufficiently
characterize the spatial-temporal properties of the background. This paper proposes a new …

Results: We applied the proposed algorithm to various video streams including
indoor/outdoor scenes taken with an IEEE-1394 camera/a normal camcorder. The IEEE …

针对鲁棒主成分分析(RPCA) 模型未能有效地利用运动目标时空连续性先验,
容易将背景中的动态细节误判为运动目标的问题, 提出了基于分层RPCA 的运动目标检测方法 …

In this paper, the RGB ratio is defined according to a reference color so that an image can be
transformed from a conventional color space to the RGB ratio space. Different to traditional …

This paper describes a simple, robust and efficient framework for background subtraction
and cast shadow suppression in complex wavelet domain. A background subtraction …

We propose an advanced visual hull technique to compensate for outliers using the
reliabilities of the silhouettes. The proposed method consists of a foreground extraction …
