| 摘 要： | 钙化信息是乳腺癌早期诊断的一个重要依据,针对钙化点检测检出率较低和假阳性较高的问题,提出一种基于多尺度空间滤波和l1范数最近邻分类的乳腺图像微钙化点检测算法.首先利用多尺度空间滤波方法得到原图像的多尺度显著特征图,然后通过基于人眼视觉特性的钙化点分割方法得到粗检测钙化点的二值图像,并送入l1范数最近邻分类器去除假阳性点...

| Abstract: | The microcalcification information is an important foundation for the diagnosis of breast cancer.In order to improve the problem of true-positive and false-positive in microcalcifications detection,a novel microcalcifications detection algorithm of mammograms based on multi-scale space filtering and l1norm nearest-neighbor(l1-NN) classifier is proposed.Firstly the multi-scale salience feature images are obtained by using multi-scale space filtering for original images,then the coarse detected binary image o... |
