This library contains helper functions to read image frames into matlab from Video file using DirectShow. This library has borrowed codes from Ashwin Thangali s "DirectShow (DirectX) based AVI file reader", and it can read multiple video formats besides avi. Features: a) can read frames from rmvb, avi, etc. b) handles most codecs installed on the system d) its implementation is only based on the IMediaDet interface -- Depending on your Matlab version, the .mexw32 files may need to be renamed as .dll -- The library usage is as follows, [avi_hdl, avi_inf] = dxVideoOpen(avi_filename) pixmap = dxVideoReadMex(avi_hdl, frame_num) img = reshape(pixmap,[avi_inf.Height,avi_inf.Width,3]) dxVideoCloseMex(avi_hdl) -- recompile the library I have compiled the code with the DirectShow lib in Microsoft DirectX 9.0 SDK Update (December 2004) -- known limitation a)only works for windows :( b)may be slow for big image frames and some codecs.

毕业设计有用，供做算法研究人员参考，小波包分析提取振动信号中的特征频率。( Graduation useful Algorithm for researchers to do reference, Wavelet packet analysis to extract vibration signal characteristic frequency.)

本程序是矩形波的产生。第零步定义了要产生的波形的所有特征参数，矩形波的持续时间WIDTH，矩形波的采样点数POINTS,载波频率为F0，这个频率的最终引入是便于使用RF频率发射波形。第一步包括产生矩形波，并将其调制到RF上，注意，产生的信号的持续时间是矩形波宽度的5倍，这样，总的采样点数就是5*POINTS。同时还应注意，如果要产生一个基带信号，必须设置T0=0.第二步是画出所产生矩形波的源代码。( This procedure is rectangle wave production. Step to produce stage defined the waveform of all characteristic parameters, the duration of the rectangle wave WIDTH, rectangle wave sampling POINTS POINTS, carrier frequency F0, this frequency for the ultimate introduction is easy to use RF frequency emission waveforms. The first step including generating rectangle wave, and modulated to RF, attention, produce the duration of the signal is five times the width of rectangle wave, so, overall sampling POINTS is 5* POINTS. Also, note that if you want to produce a baseband signals must set T0 = 0. The second step is to draw a rectangular wave generated by the source code. )
