| 摘 要： | 为实现数字乳腺图像中钙化点的自动检测,提出一种利用小波变换实现乳腺图像增强从而抑制背景,凸出钙化点的检测方法.首先对乳腺图像进行预处理提取出乳腺区域,采用方形网格覆盖乳腺区并分割出感兴趣区域(ROI),对ROI进行小波图像增强,使钙化点与背景明显的区分开来,然后采用Top-Hat算法实现钙化点的自动检测.MATLAB仿真实验结果表明,用小波变换方法增强乳腺图像,能够很好地区分图像中的钙化点与背景,基于Top-Hat算法的钙化点自动检测方法能够有效的检测出图像中的钙化区.

| Abstract: | Aimed at suppressing strong background and enhancing calcification points,this paper introduces a wavelet transform-based method for the automatic detection of calcifications in digital mammograms.The method consists of extracting the breast region by preprocess,using a square grid to divide the whole image to cover the breast area of interest(ROI),enhancing ROI by the wavelet decomposition,suppressing backgrounds so as to strengthen calcification,distinguishing calcification points from the background,and ... |
