首先生成如下形式的图片：图中的白条为7象素宽，210象素高，白条间的宽度为17象素。

应用多种滤波器进行处理：算术均值，几何均值，谐波均值，逆谐波均值，中值滤波，中点滤波，最大值、最小值滤波等。注意，需改变模板大小。

-Pictures first generate the following form: in IOUs 7 pixels wide by 210 pixels high, IOUs between the width of 17 pixels. Apply a variety of filters for processing: arithmetic mean, geometric mean, harmonic mean, inverse harmonic mean, median filtering, the midpoint filtering, maximum, minimum filter. Note that the need to change the template size.
