1. to calculate FFT real-time 2. to control the brightness of your picture real time 3. to make frames from your audio files

采用共信息(mutual information)实现了图像对齐的功能（image registration）。这在数据融合，图像处理里是很重要的。(adopt information (mutual information) to achieve alignment of the image features (i MAGE registration). This data integration, image processing, was very important.)

说明：  this is water mark code

分析信号谱峭度根据最相关性，提取敏感频段，进一步分析。(The kurtosis of the signal spectrum is analyzed according to the most relevance, and the sensitive frequency bands are extracted for further analysis.)

matlab图形处理算法，基于 Hough 变换或改进的 Hough 变换对图像中的圆形目标进行识别。(matlab image processing algorithms based on Hough transform Hough transform or improve the image of the circular target recognition.)

matlab仿真卷积码与理论值的区别以及误码率的仿真(matlab simulation convolutional codes with the theoretical value of the difference between the simulation and the error rate)

设计一个数字滤波器，在频率低于 的范围内，低通幅度特性为常数，并且不低于0.75dB。在频率 和 之间，阻带衰减至少为20dB。 (1)试求满足这些条件的最低阶Butterworth滤波器。(Design a digital filter, in the range of frequencies below the low-pass amplitude characteristic is constant, and not less than 0.75dB. Between the frequency and stop-band attenuation of at least 20dB. (1) Determine the lowest-order Butterworth filter to meet these conditions.)

一个用simulink做的模糊PID自适应系统，FIS等都比较简单，适合初学者。通过与PID的比较曲线可以看出此系统更加优越。(A simulink do with self-adaptive fuzzy PID system, FIS are relatively simple, suitable for beginners. Comparison with the PID system curve can be seen even more superior.)

离散数据频谱分析，采样数据进行离散后，获取信号中的周期运动信息(matlab，FFT，frenquence chart)
