vb6.0的验证码处理，在去除干扰点时，采用中值滤波是一种不错的方法，中值滤波法是一种非线性平滑技术，它将每一像素点的灰度值设置为该点某邻域窗口内的所有像素点灰度值的中值。中值滤波的实现方法

进制转换的一个很好的函数。可在16进制内自由转换，也可创新地使用5、6、7等进制格式。经过简单改造后可使用最大36进制的形式。是编程人员的一个好东东。-base for the conversion of a good function. 16 in the 229 free conversion, but also innovative use of 5, 6, 7, etc.-band format. After simple transformation can be used after the 36 largest 229 forms. Programming staff is a good Eastern.
