查询词典 computed

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。
