| 摘 要： | 提出一种基于Graph Cuts的多尺度乳腺肿块自动分割方法.首先,应用区域统计融合方法对图像进行粗分割,将得到的粗轮廓作为后续Graph Cuts分割的初始轮廓.在迭代优化阶段,引入多尺度分析方法,以高斯金字塔分解得到的多尺度图像序列代替固定尺度的原始图像序列估计高斯混合模型(GMM)参数,将粗糙尺度的易分割性与精细...

| Abstract: | A novel scheme for mass segmentation in mammography is proposed,which is based on Graph Cuts algorithm and multi-scale analysis.Mammogram is segmented by statistical region merging firstly,and the obtained rough contour is used as the initial contour for Graph Cuts segmentation.In iterative optimization stage of the algorithm,multi-scale analysis method is introduced to estimate the Gaussian Mixture Model(GMM)parameters with pyramidal decomposing serial images instead of fix-scale original image.The algorit... |
