第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)

在matlab中bayes和Fisher分类器设计的小程序代码，实现垃圾邮件和正常邮件的分离，比较不同维度，不同样本，两种分类器正确率的优劣，适合初学者学习(In matlab the bayes and Fisher classifier design a small program code, junk mail and regular mail to achieve the separation of comparing different dimensions, different samples, the correct classification rate of both the pros and cons, suitable for beginners to learn)

使用Matlab开发的设计凸轮的源程序，使用了向量法的设计方法。设计了一个正弦运动规律的凸轮，程序带有较完整的注释，对于初学凸轮设计的人来说应该是一个比较好的参考。(It s the source code of the design of a cam using matlab, which uses the method of vector.)

圆周卷积 的matlab实现法。对matlab新手适用。(Circular convolution in matlab implementation method. On the matlab novice apply.)
