利用数据点的密度大小作为权值，借助数据本身的分布特性，提出了一种点密度加权模糊c -均值算法。

A dot density weighted fuzzy C-means algorithm is proposed by using density size of data dot regarded as weighted value and distributing characteristic of datas own.

中值滤波是图像处理中比较常用的滤波方法，但是它对窗口和数据点的依赖使它在处理空间密度较大的冲激噪声时受到限制。

The median filtering is a common method in image processing, but it is limited when it faces the swash noise of space high density, because it depends on the fixed Windows and the data points.

从各子块中取出数据点密度较大的像素组成样本块。

Then select certain larger density pixels in each subset to construct corresponding swatch.
