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)

Now interchange the “b” and “w” in the two words “be” and “we.” In splicing, be careful that you capture all important perceptual cues of the two phonemes. What is the effect? Can you interchange the two words by interchanging the two initial phones?

用分步傅里叶变化法求解非线性薛定谔方程，适用于非线性光纤系统(split_step_fourier method for nonlinear fiber optic)

说明：  这是利用改进的kalman滤波来处理GPS信号，通过与传统的kalman滤波比较得到较好的效果。直接解压，就可以导入work里运行。(This is the improved GPS kalman filter to process the signal, by comparison with the traditional kalman filter get better results. Direct decompression to work can be imported to run. )

说明：  ％code2_1 for lecture 1 Simpson s rule ( Code2_1 for lecture 1 Simpson s rule)

用于图像提取圆形区域，可以自定义半径大小及圆心位置，也可以在图像当中点取(extract image round areas)

利用维纳滤波的方法进行语音信号的降噪处理，适用于语音增强领域(The denoising processing of speech signal by Wiener filtering is suitable for the domain of speech enhancement)

说明：  输入特征向量训练随机森林分类模型，并计算分类结果的Kappa系数，混淆矩阵，准确性，特异性和敏感性。(Input eigenvector to train random forest classification model, and calculate kappa coefficient, confusion matrix, accuracy, specificity and sensitivity of classification results.)
