说明：  本书的存在归功于网络及自由软件运动所实现的合作方式。它的三位作者---一位大学教授、一位高中老师，以及一位专业程序设计师---尚未见过面，但是我们已经能够紧密合作，并且受到许多愿意付出时间与心力的杰出人士帮助，使得这本书更臻完善。(TThe Book owes its existence to the collaborative approach of the Internet and the Free Software Movement. Its three authors, a university professor, a high school teacher, and a professional programmer, have yet to meet, but we have been able to work closely together and have been helped by many outstanding people who are willing to devote their time and effort to making the book more perfect.)

this is exe. file will be useful to you.

说明：  小波分解的入门级教材，内容不多，但讲解平实，简单易懂，可以作为刚开始学习小波的同学的阅读材料(wavelet decomposition of the entry-level teaching materials, as small, but on the down-to-earth, simple, as it has just begun to study wavelet students reading material)

旅行商问题，两种方法实现，分别是递归回溯和用栈来代替递归的功能的程序-Traveling salesman problem, two methods to achieve, namely, retrospective and the use of recursive stack instead of recursive function procedures

一个复数运算的类-a complex computing category

8 通道双正交余弦调制滤波器组实现，滤波器的采样频率为 Fs:20000Hz 设计的低通原型的通带频率为625Hz 阻带衰减80db，滤波器的系数长度为512-8-channel biorthogonal cosine-modulated filter banks to achieve, filter sampling frequency Fs: 20000Hz designed a prototype low-pass frequency of 625Hz passband stopband attenuation of 80db, the length of filter coefficients for 512

该方法采用反对称双正交小波分解系数计算视频帧的方向梯度向量，再统计由梯度向量角和模值构成的联合空间二维直方图，然后计算连续帧直方图之间的距离，得到两帧之间的不连续值，最后采用自适应阈值分割，检测出镜头边界。-This method is the use of anti-symmetric biorthogonal wavelet decomposition coefficients video frame the direction of gradient vector, and then statistics from the gradient vector angle and modulus values constitute the joint space of two-dimensional histogram, and then calculating the histogram for the distance between frames, by the two frames between the consecutive values, the final adaptive threshold segmentation, shot boundary detected.
