Background modeling is the key technology for moving target detection implemented with the background difference method. The conventional background modeling methods cost large amount of calculation time, in order to improve the speed and precision of the model, this paper presents an improved Frame Difference Background Modeling. The frame difference background modeling was initialized by Sele...

Aiming at the problems that the classical Gaussian mixture model is unable to detect the complete moving object, and is sensitive to the light mutation scenes and so on, an improved algorithm is proposed for moving object detection based on Gaussian mixture model and three-frame difference method. In the process of extracting the moving region, the improved three-frame difference method uses th...

Moving human body detection is a significant research direction in the fields of image processing and computer vision. A new method of moving human body detection is proposed in this paper based on Kinect, which extracts depth images with Kinect, so that the moving object in which people are interested can be obtained without useless background information. Five consecutive frames of depth imag...

In this paper we prove some basic theoretical results underlying the moving frame theory of pseudo-groups developed in the first two papers in this series. The first result demonstrates that a pseudo-group that acts locally freely at some sufficiently high order acts locally freely at all subsequent orders, and thus can be completely analyzed with the moving frame method. The second result is a...

Extracting moving objects from a video shot provides a good low-level representation of videos. It provides object trajectory, color, shape characteristics. Combined with specific domain knowledge, it can be a powerful cue as what is going in a video shot. This paper proposes a unsupervised moving object extraction/tracking system that attempts to capture salient moving objects from an image se...

The prolongation of a transformation group to jet bundles forms the geometric foundation underlying Lie’s theory of symmetry groups of differential equations, the theory of differential invariants, and the Cartan theory of moving frames. Recent developments in the moving frame theory have necessitated a detailed understanding of the geometry of prolonged transformation groups. This paper begins...
