The method consists of tree steps: enhancement, contour segmentation, and feature selection. In this study, our method is able to enhance the signals from masses and extract the useful contour feature from the segmented regions. The ruler method of fractal dimension computed for each case was used to form a contour feature. These feature measures can be input to a classifier based on sorting. The experimental results show that our scheme can provide useful contour extraction for spiculation structures in mammographic images.

我们的研究目的是在乳房的X光影像中选取肿瘤怀疑的区域，分成三步骤，影像前处理、轮廓分割、特徵选取，找出具有星状物轮廓的肿瘤，我们的方法首先强化肿瘤组织，接著有效分割出肿瘤的轮廓，最后利用规则式的碎形维度计算其轮廓特徵值，接著排序分出肿瘤轮廓类别，实验结果证明我们的方法可有效侦测出星状物肿瘤轮廓及其特徵。

Ji: :: The current thesis adopts a movement analysis on the Binding Principles. The feature determines the clitic zi observing Binding Principle A. It undergoes CliticizationLF that is it adjoins to I in its local domain. Thus zi gets adjacent to the specifier of I, which values the unvalued person feature of zi through Feature Copying and checks against the person feature of zi.

接语词&自&的特征决定其执行约束原则A，进行接语词化Cliticization_(LF，即在逻辑式里隐性移位到其局部管辖语域内的功能语类上I，这样就与I的标语词形成相邻关系，通过&特征复制&，I的标语词为&自&的人称特征赋值，并相核查。

In this regard, the research trend of globalization of competition has been positively open up. In this paper a novel simulated annealing feature uniformity band selection approach is proposed for the feature extraction of the hyperspectral remote sensing images. The simulated annealing band selection method has been successfully applied to the feature extraction of the hyperspectral images by clustering highly correlated hyperspectral bands into a smaller subset of band modules based on simulated annealing algorithm. SAFU built by SABS is an efficient feature extraction method.
