This study＇s objective was to investigate the Guguan-Xiangong Fault, which lies in the southern Liupanshan area, through satellite image interpretation and field observations. Guguan- Xiangong Fault is divided into five subsegments; among these, the Badu-Longwei segment has been the most recently active. The geomorphic features of the Badu-Longwei segment are clearly displayed, including multiple high fault scarps with fresh bedrock free faces. There is significant evidence for Holocene activity of the three fault sections, located in Renhuashu, Tianjiagou, and Xinjiecun respectively. The three sections feature distinct episodic deposition and fault scratches. Based on 14C- dating and field observations on the three fault sections, two or more paleoearthquakes across the Badu-Longwei fault segment are ascertained, between 5874±116 and 5430±140 a BP, and after 2037±83 a BP respectively. The Badu-Longwei segment of the Guguan-Xiangong Fault is preliminarily extrapolated as the seismogenic structure of the 600 A.D. Qin-Long earthquake.

稀疏表示近些年来被广泛用于人脸识别。由于在现实中,同类图像之间往往不可避免存在光照、姿态、甚至遮挡等差异,如果使用这些有各种差异的图像样本去表示某一特定状态下的图像,则表示的效果势必会受到影响。为进一步提高稀疏表示在人脸识别中的性能,基于原始协同分类(CRC)算法,引入近邻思想,即在各类训练样本中分别寻找与测试样本相近的若干样本,以构建新的近邻样本集;在此基础上进行协同表示,并利用每类样本系数分别重构待测样本,最后基于重构样本集再次协同表示。这种基于近邻样本的二次稀疏重构表示法,使识别更精确,并在一定程度上提升了运行效率。在ORL,YALE,FERET及AR人脸数据库上通过仿真验证了该方法的有效性。

基于整个数据集的稀疏表示(sparse representation classification,SRC)用于人脸识别在很大程度上影响了运行效率。如何利用较少样本稀疏表示在保证计算效率的同时,识别率也有一定提升,尤其是面对光照、角度、姿态等非受控环境,目前仍是一个问题。考虑到协同表示(collaborative representation classification,CRC)基于l2范数稀疏求解的优势,为进一步提升CRC的整体分类性能,引入类内近邻,提出一种二次近邻稀疏重构表示法。该方法首先在原始训练集上选择各类训练样本中与待测样本距离相近的若干样本组成近邻样本集,并协同表示,接着分别用各类近邻样本重构待测样本,再次选择与待测样本相近的若干重构样本协同表示,最终实现模式分类。在ORL和FERET数据库上的仿真实验表明,相比现有的一些CRC算法,该方法在一定程度上缩短了运行时间,并使识别更精确。
