说明：  这是一个关于hht变换很有用的工具箱，可以下载试一下。(This is a transformation on hht very useful toolkit can be downloaded try.)

这是用来仿真无线定位技术的算法源程序，希望可以帮到大家(This algorithm is used to simulate wireless location technology source, I hope you can help)

spectral subtraction code implementation

实现了1D,2D,3D空间自由度下的运动参数的扩展Kalman滤波算法，文章2008 IROS Visual SLAM for 3D Large-Scale Seabed Acquisition Employing Underwater Vehicles的具体实现。(a novel technique to align partial 3D reconstructions of the seabed acquired by a stereo camera mounted on an autonomous underwater vehicle. Vehicle localization and seabed mapping is performed simultaneously by means of an Extended Kalman Filter. Passive landmarks are detected on the images and characterized considering 2D and 3D features. Landmarks are re-observed while the robot is navigating and data association becomes easier but robust. Once the survey is completed, vehicle trajectory is smoothed by a Rauch-Tung-Striebel filter obtaining an even better alignment of the 3D views and yet a large-scale acquisition of the seabed.)

相似迭代算法，求解坐标变换矩阵以及位移向量，在视觉定姿中有用(Similar to the iterative algorithm, solving the coordinate transformation matrix and displacement vector, useful in the visual attitude determination)
