一个利用小波变幻实现滤波的算法

本程序实现图像的正交变换，包括傅立叶变换，离散余弦变换，沃尔什变换。-This procedure realize orthogonal transformation images, including Fourier transform, discrete cosine transform, Walsh transform.

一款图片转换为ASCII码艺术画的软件，完全开放源码，同时还采用了.ini文件保存技术，使代码更少。还可以修改ASCII字符的默认亮度等，是一款不可多得的BBS利器。-converted to ASCII art painting software, a completely open-source, and also used that. Ini document preservation technology, code less. Also ASCII characters can modify the default brightness, is a rare BBS weapon.

多种方法（软硬阈值、自适应阈值等）进行小波去噪的matlab程序-A variety of methods (hard and soft threshold, adaptive threshold, etc.) of the matlab wavelet denoising procedures

可使用数学方法生成波形声音文件的源代码.-Use mathematical method to produce a wave sound file of the source code.

一个具体的小波变换实现源代码； wavelet 子目录中存放的是基本的小波处理函数代码； wavelet_plugin 子目录中存放的是.dll的实现代码。- A concrete wavelet transformation realization source code; In the wavelet child directory deposits is the basic wavelet processing function code; In the wavelet_plugin child directory deposits is dll realization code.

小波变换，D4尺度函数和小波函数图形绘制-Wavelet transform, D4 scaling function and wavelet function Rendering

对于PCA ，LDA，BIC，EBGM都有很详细的代码。但是需要在LINUX下配置运行。不过代码较有参考价值。-For PCA, LDA, BIC, EBGM have a very detailed code. But the need to configure to run under LINUX. However, a more useful code.

利用EDA技术和FPGA在UP3开发板上实现直接数字频率综合器的设计。 实验中加入了相位控制字PWORD，用以控制相位偏移量的前四位，将相位偏移量加到ROM地址总线 上，从而引起从ROM中取得的正弦信号的偏移，实现移相信号发生器的移相功能。 实验中还加入了LCD显示功能，通过LCD显示模块器件，用LCD显示正弦信号的频率，所显示的频 率也是由频率字控制的。LCD的驱动原理同上次实验。-The use of EDA technology and FPGA development in the UP3 board direct digital frequency synthesizer design. Experiment by adding a phase control word PWORD, to control the phase offset of the top four will be added to the phase offset ROM address bus, thereby causing ROM obtained from the sinusoidal signal offset, shifted believe realize its phase-shifting function generator. Experiments have also joined the LCD display, LCD display module through the device, with LCD display the frequency of sinusoidal signal, as shown by the frequency of word frequency control. LCD driving principles with the previous experiment.
