| 摘 要： | 回顾了信号的一维小波变换多尺度过零点（MZC）表征的完全稳定的重建理论，分析了MCZ表征与小波各尺度分解的平均功率的关系；并利用医学超声图像的不同区域MZC随尺度的变化曲线参数，实现了医学超声图像的区域分割。

| Abstract: | The complete and stable reconstruction theory of zero-crossings representation of signals is reviewed. The relationship between Multiscale Zero-Crossings (MZC) representation and energy of multiscale wavelet ransform is presented. As an example, the transformation parameter of MZC for various scales in different segments of ultrasound medical image is analyzed to realize the ultrasound image segmentation. |
