A Flexible Moving Objects Segmentation Method

Zhao Yanling,Zhang Zhichao,Gao Zhenming,Zhang Qingchao

Strategic Study of CAE 2006, Volume 8, Issue 5,   Pages 84-87

Abstract:

The segmentation for moving pictures is important in content-based video encoding and video retrieval. The method of moving object segmentation is proposed with spatio-temporal threshold information. The method does well in functional agility. Its alterability depends on real conditions. The experiments show that the method can get a better result with less runtime.

Study on a kind of new strengthening buffer operators and numerical simulations

Cui Jie,Dang Yaoguo,Liu Sifeng,Xie Naiming

Strategic Study of CAE 2010, Volume 12, Issue 2,   Pages 108-112

Abstract:

According to the theory of prior using of new information,based on the research of already existed strengthening buffer operators, some new strengthening buffer operators are established. Meanwhile,their characters are studied. The flaw that the existing strengthening buffer operators can,t fully use new information of the data sequence is overcame. The problem that there are some contradictions between quantitative analysis and qualitative analysis in pretreatment for vibration data sequences is resolved effectively. An example simulation shows, compared with the existing strengthening buffer operators, the kind of new strengthening buffer operators increases the forecast precision of GM(1,1) remarkably.
