读取ply三维数据时,可采用改程序对读取的矩阵数据进行的预处理,从而便于在matlab上直接使用数据.(Read ply three-dimensional data, the program can be used to change the matrix to read the data pre-processing, so as to facilitate the use of data directly in matlab.)

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)

脆弱水印提取算法，与embed.rar中的嵌入算法相对应，可以提供较好的篡改定位(Fragile watermark extraction algorithm, and embed.rar correspond to the embedding algorithm can provide better tamper positioning)

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)
