对数据进行频谱分析

PCNN image processing neural network

matlab中的相关算法已通过验证，以及声音谱的对比(matlab related algorithms have been validated, as well as the voice of spectral contrast)

里面有一些matlab的一些命令，使新手更易查找(There are some matlab command novice easier to find)

matlab 两种写出泊松分布序列的程序(matlab possion code)

这是东南大学信息科学与工程学院《数字信号处理 第二版》第四章的实验，关于IIR 滤波器的( This is the School of Information Science and Engineering, " Digital Signal Processing Second Edition" Southeast University experiment of Chapter IV, on IIR filters)

改进粒子群算法摄像机标定，对所求的初始参数进行非线性优化,得到最终的摄像机参数精确值(Camera Calibration Using Modified Particle Swarm Algorithm， the accuracy, stability and global search ability are obviously enhanced compared with the traditional calibration algorithm. Nonlinear optimization to the desires of initial parameters, we get the final accurate camera parameters)

离散小波变换是指在特定子集上采取缩放和平移的小波变换，是一种兼具时域和频域多分辨率能力的信号分析工具。此变换运用可以缩放平移的小波代替固定的窗进行计算分析，主要应用于信号编码和数据压缩。(Discrete wavelet transform refers to the specific subset take scaling and translation on the wavelet transform, is a kind of multi-resolution ability both time domain and frequency domain signal analysis tool. This transformation can use zoom translational wavelet calculation and analysis instead of the fixed window, mainly used in signal coding and data compression. )
