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.)

支持向量机方法，用matlab实现，用于分类检测、模式识别，人脸检测等(matlab implementation for classification detection, pattern recognition, face detection, etc.)

设计抗混叠FIR滤波器实现数字下变频的设计(Design of anti-aliasing FIR filter design for digital down conversion)

说明：  folyd用来处理图论中最短路径问题。对传统的folyd算法进行了优化。(folyd to deal with the shortest path in graph theory problem. Folyd the traditional optimization algorithm.)

Matlab强大的数值计算功能与数据可视化功能，阐述了使用Matlab进行程序设计的几则经验(Matlab powerful numerical computing and data visualization capabilities, describes the use of Matlab for programming experience Ikunori)

matlab二维海面剖分，在matlab环境下实现海面模拟，并进行有限元剖分(two-dimensional surface mesh matlab)

此程序用于实现结构的有限元计算：将patran中的模型的bdf文件中的单元信息和节点信息保存成txt文档，在matlab中调用，就可实现刚度矩阵、质量矩阵的组装，进而有限元计算(This procedure is used to achieve the structure of the finite element method: bdf file of the model in patran unit information and node information is saved into a txt file called in matlab, you can achieve the stiffness matrix, mass matrix assembly, and then the finite elementcalculate)

这是一个matlab的一本比较基础的书，里面包括所有matlab课程的所有内容。(This is a matlab a basis of comparison of the book, which includes all courses in all the contents of matlab.)

This MATLAB M-file will produce the FDTD solution of a z-directed line source in a two-dimensional TMz computational domain excited.
