In this paper, we propose a novel approach that combines particle filter tracking and 3D graph cut based segmentation to achieve silhouette tracking against drastic scale change and occlusion. The segmentation module offers particle filter tracking procedure the target shape information to compensate spatial information loss in the histogram based particle filter tracking process. Meanwhile, particle...
In this paper, a novel multi-cue collaborative kernel tracking algorithm is proposed. A new constraint based on the property of cross ratio invariant enables tracking of objects insensitive to complex motions, including scale changes, rotation and especially views changes, without labeling and training. Meanwhile, invariant moments are introduced into the kernel based tracking method as the shape...
Cu2O nanorods with extraordinary large surface area are synthesized by polyol method successfully. Their photocatalytic property is evaluated by the photodegradation of brilliant red dye under visible light irradiation. For comparison, Cu2O nanocubes are synthesized and evaluated with photocatalytic property as well. The results show that the photocatalytic activity of the Cu2O nanorods is more than...
