This paper introduces a novel automatic video object extraction algorithm based on combination of color and motion segmentation results. The algorithm includes five parts: preprocessing, color segmentation, motion segmentation, combination of color and motion segmentation of multiple frames, post-processing. The performance of this algorithm is very(More)
In this paper, we propose a robust video object extraction algorithm using background subtraction. The algorithm combines two statistical features of the background subtracted images to extract the objects. This method can produce satisfying results with pixel-wise precision. Furthermore, it is robust to the effects of camera noise and the changing of(More)
OBJECTIVE To observe the effects ofGynura segetum in rats with hepatic veno-occlusive disease (HVOD). METHODS Sixty Sprague-Dawley rats were assigned to a blank control group, one of three Gynura segetum treatment groups (low-dose group, 5.0 g/kg; mid-dose group, 10 g/kg; high-dose group, 20 g/kg), or a pseudo-drug group (10 g/kg of pseudo-ginseng). After(More)
The ability of flow cytometry to allow fast single cell interrogation of a large number of cells has made this technology ubiquitous and indispensable in the clinical and laboratory setting. A current limit to the potential of this technology is the lack of automated tools for analyzing the resulting data. We describe methodology and software to(More)
AIMS Evidence shows that aberrant expression of long non-coding RNA (lncRNA) is closely associated with tumor development and progression. However, the role of lncRNA in environmental carcinogen induced gastric tumorigenesis remains largely unknown. This study aimed at investigating the function role of lncRNA in N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)(More)
