we present an improved fuzzy
C-means (FCM) algorithm for image segmentation by introducing
a tradeoff weighted fuzzy factor and a kernel metric. The
tradeoff weighted fuzzy factor depends on the space distance of
all neighboring pixels and their gray-level difference simultaneously.
By using this factor, the new algorithm can accurately
estimate the damping extent of neighboring pixels. In order to
further enhance its robustness to noise and outliers, we introduce
a kernel distance measure to its objective function. The new
algorithm adaptively determines the kernel parameter by using
a fast bandwidth selection rule based on the distance variance
of all data points in the collection. Furthermore, the tradeoff
weighted fuzzy factor and the kernel distance measure are both
parameter free. Experimental results on synthetic and real images
show that the new algorithm is effective and efficient, and is
relatively independent of this type of noise.

Matlab函数 采集一段浊音和清音语音信号
（1） 使用录音软件或者Matlab函数，分别采集一段浊音和清音语音信号（是你自己说的，如：a，o，s等），采样率为8KHz，量化精度为16比特线性码，存在自己指定的目录下，例如D盘根目录下叫sound的文件夹中，录音文件名为yourfilename_a.wav，yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。
（2） 根据语音信号的短时平稳特性，分析帧长取30ms（或10ms～50ms）；
（3） 利用上述基音提取的三种方法（任选两种方法）的编程流程图（图1、图2和图3）编制浊音语音基音提取的matlab程序，上机调试给出相应波形，并根据图形，分析计算出基音周期。所用公式为：
(1.5)
其中 是基音脉冲处所对应的位置， 是抽样频率， 是基音周期。
（4） 将语音信号换为清音语音，运行程序，与浊音语音的运行结果进行比较，并得出结论。
