PID-Tunning-with-PSO

峰值信噪比的源函数，数值越大，表示图像越清晰，反之，图像模糊。(Source function peak signal to noise ratio, the greater the value, the image is more clear, on the contrary, the image is blurred.)

matlab web 技术，通过这个技术，能让不会使用matlab的人使用matlab(matlab web technology, the adoption of this technology, can not use matlab to use matlab)

DCT 2D function for signal

读取segy数据、文件，写道头卷头等等，内置说明书，简单易用(Read the segy data, file, writes head roll and so on, the built-in instructions, easy to use)

说明：  This interface specifies the methods for a visitor of Constant objects.

hartley and colpitts oscillator c program

将COMTRADE格式的数据转换成为真实的电气量值，并绘制波形(COMTRADE format of the data will be converted into actual electrical value, and draw the waveform)

Evaluate frequency spectrum of signals

一本介绍采用MATLAB工具进行系统仿真分析的典书籍，主要是时频分析(One describes the MATLAB tools for System Simulation Code books, mainly time-frequency analysis )

High accuracy optical flow using a theory for warping(The files optical_flow_brox.m and optical_flow_sand.m are the files you need to run. optical_flow_brox.m implements the traditional algorithm. Just replace the first lines where images are read, with your image, and start the process. optical_flow_sand.m implements a variant presented in CVPR 2006. Again just replace the lines "img1 = imread( ... )" and "img2 = imread( ... )" with your images and the rest is automatic. The variable num_levels controls the number of images in the laplacian pyramid to be constructed. Change it to suit your convenience.)
