捷宇 高拍仪 demo SDK

说明：  解决散斑图像的重建问题,主要是使用了相位恢复算法(to study the picture problem)

说明：  小波阈值去噪。对灰度图像和二值图像进行滤波。(Wavelet thresholding filter . Denoiseing for the gray image and binary image .)

使用canny边缘检测算法，提取图像轮廓(Canny edge detection algorithm is used to extract image contour.)

说明：  基于相位梯度法PGA的 Matlab 估计相位误差 估计多普勒中心(Estimation of Phase Error and Doppler Center by PGA MATLAB)

说明：  简单的数字图像处理程序，实现灰度化，二值化，边缘检测等(Simple digital image processing program, graying, binarization, edge detection, etc....)

小波去噪,实现阈值小波去噪，并且含有frost去噪，并且输出信噪比(Wavelet denoising, to achieve the threshold wavelet denoising, denoising and contains frost, and the output signal to noise ratio)

说明：  有注释的粒子滤波程序。粒子滤波(PF: Particle Filter)的思想基于蒙特卡洛方法(Monte Carlo methods)，它是利用粒子集来表示概率，可以用在任何形式的状态空间模型上。(Annotated particle filter program. Particle filter (PF: Particle Filter) Monte Carlo method based on the idea (Monte Carlo methods), which is set to represent the probability of a particle can be used in any form of state space model.)

说明：  利用马尔可夫模型检测分割图像，获得MAP准则下的图像分割结果(??????????í ?? ?? ?? ?? ò?? ?? ???? ?? ì ?? ?? ?? ?? ???? ?? ???? ?? ?? ????μ??MAP × ?? ??ò????μ???? ?? ???? ?? ?? ?? ?? á ?? ??)

MATLAB的一个源文件。用差分直方图位移的可逆数字水印实现图像的完整性认证。(MATLAB as a source file. Histogram using differential displacement reversible digital watermarking images realize the integrity of certification.)
