为了在滤除图像噪声的同时更好的保护图像的细节,文中提出了一种基于非线性自适应滤波结构的改进算法。用中心加权中值滤波算法代替原方法中的中值滤波算法以及中值滤波代替均值滤波作为最终滤波结果输出。这种算法与同类算法相比,具有更好的滤波性能并能更好的保护细节,其效果明显优于中值滤波算法。 相似文献

ABSTRACT The speed performance is involved not only in linear sprints, but also in a wide spectrum of multi-directional movements, such as curve sprinting. Curved sprint can be defined as sprint with gradual and continuous change of direction (COD). Although ~85% of the actions performed at maximum velocity in a professional soccer league are curvilinear sprints, there is not any specific test to assess this ability. This study aimed to analyse the reliability of a new curve sprint test, and compare its results with those obtained by soccer players in linear sprint. Forty experienced soccer players performed 3 attempts of curve sprint (using the penalty arc) to right and left side (17 m), and 3 linear sprints (17 m) in two different days. The ICCs (inter-session reliability) were 0.93 for sprint curve right side (CSRS) and 0.89 for sprint curve left side (CSLS), considered “acceptable”. The CVs (intra-session reliability) were 0.87% in CSRS and 1.15% in CSLS. The coefficient of determination (R2) between linear and curve sprinting was ~35%. The association between curve sides was “very large” (r = 0.878; p < 0.01). In summary, we showed that “curve sprint test” is highly reliable, and that curvilinear and linear sprints are different and independent actions. 相似文献

Previous studies of academic web interlinking have tended to hypothesise that the relationship between the research of a university and links to or from its web site should follow a linear trend, yet the typical distribution of web data, in general, seems to be a non-linear power law. This paper assesses whether a linear trend or a power law is the most appropriate method with which to model the relationship between research and web site size or outlinks. Following linear regression, analysis of the confidence intervals for the logarithmic graphs, and analysis of the outliers, the results suggest that a linear trend is more appropriate than a non-linear power law. 相似文献

从线性到非线性:企业成长理论回顾、现状与展望 总被引：2，自引：0，他引：2
从最初企业是生产函数、契约到企业是复杂适应系统的认识深化,企业成长的理论研究开始从线性向非线性过渡。本文以企业成长理论从线性到非线性转变为主线,梳理企业成长理论的演进脉络。通过对众多理论之间的内在逻辑关系及其适用边界和应用性分析发现,非线性在企业成长过程发挥了主导作用,并指出从内生和外生两方面互动的视角建立非均衡、非线性有机统一的企业成长机制,可对企业成长规律给出更合理的理论解释。 相似文献

From the way that it was initially defined (Hirsch, 2005), the h-index naturally encourages focus on the most highly cited publications of an author and this in turn has led to (predominantly) a rank-based approach to its investigation. However, Hirsch (2005) and Burrell (2007a) both adopted a frequency-based approach leading to general conjectures regarding the relationship between the h-index and the author's publication and citation rates as well as his/her career length. Here we apply the distributional results of Burrell, 2007a, Burrell, 2013b to three published data sets to show that a good estimate of the h-index can often be obtained knowing only the number of publications and the number of citations. (Exceptions can occur when an author has one or more “outliers” in the upper tail of the citation distribution.) In other words, maybe the main body of the distribution determines the h-index, not the wild wagging of the tail. Furthermore, the simple geometric distribution turns out to be the key. 相似文献
