contourlet 小波，直方图的三种图像增强程序(failed to translate)

ICP算法,主要用于三维点云数据的配准，最近点迭代算法，可以收敛到局部最小(registration of point cloud data,the iterated close point algorithm)

对二维数据进行变分模态分解，可用于地震数据去噪等(Variational mode decomposition of two-dimensional data can be used for seismic data denoising, etc.)

说明：  VC图像处理，对初学者和研究者有一定的参考作用。(VC image processing, for beginners and researchers are certain references.)

欧洲winner2的官方3D天线信道模型源程序 内包含十多种场景选择 考虑了角度扩展 k参数等(H=WIM(WIMPAR,LINKPAR,ANTPAR) is a 5D-array of channel coefficients. For explanation of the input parameter structs, see WIMPARSET, LAYOUT2LINK, LAYOUTPARSET, and ANTPARSET. H is a cell array of size K (number of links.SIZE(H{i})=[U S N T], where U is the number of MS (RX)elements, S is the number of BS (TX) elements, N is the number of paths,T is the number of time sample)

鸟瞰图矫正，从倾斜角度矫正成正面图像，实现平面图像的鸟瞰矫正(bird-view,from tilt angel to jiaozheng image)

matlab gui实现三维图形的旋转，平移及缩放(matlab gui to achieve rotation, translation and scaling of 3D graphics)
