Three dimensional vascular reconstruction

提取二值图像中的所有非零点坐标，进行矩阵标准化，最后进行二次曲线拟合(Extracting the binary image of all non-zero coordinates, matrix standardized last quadratic curve fitting)

这是一个经典的fourier translate 傅里叶变换的程序 计算图像的中心点并标记和傅里叶频谱图的最大能量环并标记(This is a classic Fourier transform fourier translate the program to calculate the center of the image and mark and Fourier frequency spectrum of the maximum energy ring and mark)

利用Artoolkit实现了虚拟现实的算法，VS2008下测试通过(Use Artoolkit algorithm to achieve a virtual reality, VS2008 under test)

应用MATLAB小波工具箱中的一维小波包分析函数,采用默认阈值、调节后的阈值两种方法对含噪声的信号进行处理,并以一可见吸收光谱降噪为例,说明该方法在信号降噪中有效可行. (Application of MATLAB wavelet toolbox one dimensional wavelet packet analysis function, using the default threshold value, the adjusted threshold value of two kinds of methods including noise signal processing, and with a visible absorption spectrum noise reduction as an example to show the method is effective in signal noise reduction is feasible. )

ViBE背景建模算法，从 PC上移植改编，可在嵌入式上运行，效率较高(ViBE background modeling algorithm, coded PC to imbeded. )

说明：  通过hough变换求图像中的圆的参数（圆心坐标和半径）(Through the hough transform for image circle parameters (center coordinates and radius))

说明：  可支持手写数字识别，r和python两种语言编写，生成画板鼠标手写输入，也支持上传图片(Handwritten digit recognition)

说明：  基于opencv的小面积区域的去除.可以去除面积小于指定面积的无兴趣区域.(Opencv-based small area of the region to remove. Can remove an area of less than the specified area is not interested in the region.)

说明：  基于LEE滤波的极化SAR去噪 matlab实现(jiyu lee lvbo jihua SAR matlab)
