A novel approach for detection of multiple moving objects from binocular video sequences is reported. First an efficient motion estimation method is applied to sequences acquired from each camera. The motion estimation is then used to obtain cross camera correspondence between the stereo pair. Next, background subtraction is achieved by fusion of temporal difference and depth estimation. Finall...

We present two data-driven importance distributions for particle filterbased articulated tracking; one based on background subtraction, another on depth information. In order to keep the algorithms efficient, we represent human poses in terms of spatial joint positions. To ensure constant bone lengths, the joint positions are confined to a non-linear representation manifold embedded in a highdi...

In background subtraction, the maintenance of significant backgrounds is very critical under various scene changes. In this paper, we propose a background maintenance method for dynamic scenes including global intensity level changes caused by the changes of illumination conditions and camera settings. If global intensity level changes abruptly, the conventional background model cannot discrimi...

The background subtraction is an important method to detect the moving objects, and its difficulty is the background update. So a background reconstruction algorithm based on pixel intensity classification is presented in this paper. According to the hypothesis that the background pixel intensity appears in image sequence with maximum probability, the pixel intensity differences between sequent...

We present a novel approach to background subtraction that is based on the local shape of small image regions. In our approach, an image region centered on a pixel is modeled using the local self-similarity descriptor. We aim at obtaining a reliable change detection based on local shape change in an image when foreground objects are moving. The method first builds a background model and compare...

In this research, we propose a novel method of monitoring and tracking pedestrians in wide and open area, such as shopping mall and exhibition hall, using a number of laser range scanners (LD-A). LD-A, produced by IBEO Lasertechnik, is a single-row type laser range scanner with a high profiling rate of lOHz and wide viewing angle of 270 degree. LD-As are set on the ground doing horizontal scann...
