fuzzycmeans
Magnetic resonance (MR) images can be used to detect lesions in the brains of multiple sclerosis (MS)
patients and is essential for diagnosing the disease and monitoring its progression. An automatic method is
presented for segmentation of MS lesions in multispectral MR images. Firstly a PD-w image is subtracted its
corresponding T1-w image to get an image in which the cerebral spinal fluid (CSF) is enhanced. Then based on
kernel fuzzy c-means (KFCM) algorithm, the enhanced image and the corresponding T2-w image are segmented
respectively to extract the CSF region and the CSF combining MS lesions region. A raw MS lesions image is
obtained by subtracting the CSF region CSF combining MS region. By applying median filter and
thresholding to the raw image, the MS lesions are detected finally. Results are quantitatively uated on
BrainWeb images using Dice similarity coefficient (DSC). Finally, the potential of the method as well as its
limitations are discussed.

设r是f(x) = 0的根，选取x0作为r初始近似值，过点（x0,f(x0)）做曲线y = f(x)的切线L，L的方程为y = f(x0)+f (x0)(x-x0)，求出L与x轴交点的横坐标 x1 = x0-f(x0)/f (x0)，称x1为r的一次近似值。过点（x1,f(x1)）做曲线y = f(x)的切线，并求该切线与x轴交点的横坐标 x2 = x1-f(x1)/f (x1)，称x2为r的二次近似值。重复以上过程，得r的近似值序列，其中x(n+1)=x(n)－f(x(n))/f (x(n))，称为r的n+1次近似值(Let r is f (x) = 0 root, select the initial approximation x0 as the r, over point (x0, f (x0)) to do the curve y = f (x) the tangent L, L the equation y = f ( x0)+ f ' (x0) (x-x0), find the intersection of L and the x-axis of abscissa x1 = x0-f (x0)/f' (x0), x1 is called an approximation r. Through points (x1, f (x1)) to do the curve y = f (x) the tangent, and find the intersection of the tangent with the x-axis of abscissa x2 = x1-f (x1)/f ' (x1), x2 is called r the second approximation. Repeat the process, get an approximation of the sequence r, where x (n+1) = x (n)-f (x (n))/f ' (x (n)), as an approximation of r n+1 times)
