Description: This toolbox provides some functions for manipulating planar, closed splines to implement image or video segmentation by means of deformable (or active) contours. Contour topology is managed in a way that should allow changes similar to what can be observed with level sets (merging and splitting but no hole creation). Several objects can be segmented simultaneously in several frames. -This toolbox provides some functions for m anipulating planar. closed spline to implement image or video segm entation by means of deformable (or active) con tours.

Description: 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. -This library contains helper functions to read image frames into matlab from Video

Description: 1.基本内容
本设计目标在于利用Matlab强大的图像处理能力和实用便捷的编程方法，通过处理包含人脸的视频帧系列图像，灰度积分投影技术的眼睛定位方法，进而利用perclos计数，计算眨眼率，从而得到比较准确的疲劳状况。
2.具体要求
本设计基于灰度积分投影技术的眼睛定位方法，再结合perclos技术。首先通过图像预处理技术得到灰度分配较为均匀的图像,然后分别利用水平和垂直灰度积分投影曲线结合人脸的结构特征找到眼睛的位置坐标,实现了准确的眼睛定位,通过perclos技术技术眨眼率，根据先验值得到是否疲劳。(The goal of this design is to use MATLAB's powerful image processing ability and practical and convenient programming method, through processing the video frame series images including the face, the eye location method of gray integration projection technology, and then use PERCLOS count to calculate the blink rate, so as to get a more accurate fatigue condition.)
