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.

车牌识别系统，一个比较实用的程序，不过移植性不是很高(License plate recognition system, a more practical procedure, but portability is not very high)

自适应滤波，利用C语言实现该功能，调试正确(Adaptation using LMS)

直方图规定化，用于matlab图像处理。所谓直方图规定化，就是通过一个灰度映像函数，将原灰度直方图改造成所希望的直方图。所以，直方图修正的关键就是灰度映像函数。(Histogram specification for matlab image processing. The so-called histogram specification is through a grayscale image function, the original histogram transformed into the desired histogram. Therefore, the key is the gray image histogram correction function.)

可以求解系统的亚谐波共振,例如求解轧机振动系统的1/3亚谐波共振(You can solve the sub-harmonic resonance system)
