audio output via SSP interface microcontroller LPTS2478, in good quality. Binary code is stored in flash sound memory of the microcontroller.

文件包含fast角点检测的matlab,c,以及opencv实现，还包含有参考文献说明等。(The file contains the fast corner detection, Matlab，c, and opencv realized, also contains references descriptions.)

说明：  matlab仿真代码，基于密度的DBSCAN聚类算法，对数据进行聚类处理。(Matlab simulation code, density-based DBSCAN clustering algorithm, clustering data processing.)

光滑比的检验，用于灰色预测模型的建立过程，如果数据达不到要求，就不能用来预测(to exam it whether smooth or not)

自己写的唯一可译码判定准则，可以准确判定码组是否为唯一可译码组(Write their own unique criteria DECODABLE can accurately determine whether the code group is the only decoding group)

Matlab allows the use of MEX files –MEX files are pre-compiled files that are called from Matlab –Can be compiled from Matlab .m files –Can also be compiled from external C++ code. • This will be our focus

图1为均衡带限信号所引起失真的横向或格型自适应均衡器(其中横向FIR系统长M=11), 系统输入是取值为±1的随机序列，其均值为零；参考信号；信道具有脉冲响应： 式中用来控制信道的幅度失真(W = 2～4, 如取W = 2.9,3.1,3.3,3.5等)，且信道受到均值为零、方差(相当于信噪比为30dB)的高斯白噪声的干扰。试比较基于下列几种算法的自适应均衡器在不同信道失真、不同噪声干扰下的收敛情况(对应于每一种情况,在同一坐标下画出其学习曲线): 1）横向/格-梯型结构LMS算法 2）横向/格-梯型结构RLS算法 并分析其结果。(Figure 1 is a band-limited signal caused balanced horizontal or lattice distortion adaptive equalizer (FIR system in which the lateral length M = 11), the system input is the value of a random sequence of ± 1, mean zero reference signal channel has impulse response: Wherein the amplitude of the distortion for the control channel (W = 2 ~ 4, and so as to take W = 2.9,3.1,3.3,3.5), and subjected to a channel with zero mean and variance (equivalent SNR is 30dB) Gaussian white noise. Compare the following types of algorithm-based adaptive equalizer in a different channel distortion, the convergence of different noise interference (corresponding to each situation, draw their learning curve in the same coordinate): 1) landscape/grid- LMS algorithm ladder structure 2) landscape/grid- RLS algorithm ladder structure And analyze the results.)

网上搞到的一个处理数据的程序，可以使用的。(Data of a processing program, you can get online.)
