说明: 乳腺癌的发病率在女性癌症中占据首位,开展乳腺癌的诊断和防治研究具有重要的科学意义和临床实用价值。
文中主要研究的是对超声图像进行分析,对其灰度和纹理特征提取进行研究,并在特征选择阶段使用类间距对单个特征的分
类能力进行评价,为后续研究计算机辅助诊断系统奠定一个初步基础。

正弦周期信号的随机共振,不同于以往微弱信号检测中的抑制噪声,随机共振能通过噪声加强信号传输能力( We present the numerical method to solve the bistable SR model based on Runge-Kutta
algorithm, and propose a new kind of approach for detecting weak signal, which can effectively detect both period and aperiodic
weak signals corrupted by the strong noise background.
