dxVideo
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.

GravityCenter
该函数实现的是激光光斑中心检测。首先对光斑进行预处理,然后利用灰度重心法来计算得到光斑的中心坐标,最后利用MATLAB的绘图功能描绘出光斑中心位置的变化情况。(This function is implemented in the laser spot detection. First spot pretreatment, and then use the barycenter method to calculate the coordinates of the center of the spot, the final use of MATLAB graphics depict the changes in the spot center position.)

应用简正波理论求解下列声场:如下图所示波导模型,上层为均匀水层,其厚度为100m,声速为1500m/s;下层为硬质均匀海底,海面和海底均平整。点声源位于30m深处,辐射声波频率为25Hz,编程计算10m和90m深度上的传播损失,分析其差别。(The normal wave theory is applied to solve the following sound fields: the waveguide model shown in the following figure shows that the upper layer is a uniform water layer with a thickness of 100m and a sound velocity of 1500m/s; the lower layer is a hard uniform seabed with smooth surface and seabed. The point source is located at the depth of 30m and the frequency of radiated sound wave is 25Hz. The propagation loss at the depth of 10m and 90m is calculated by programming, and the difference is analyzed.)
