含实验报告以及测试数据 基于离散点的构TIN算法 一、算法思想 （1）首先，找出离散点集中相距最近的两点，连接这两点形成TI、的初始基线。  （2） 然后，找出包含此基线的另外一个点构成三角形。寻找第三点的方法: △按Delaunav三角形的判断法则乎找第三点。 △或者.按距离基线中点最近的原则挤找第三点。 （3）连接孰点与基线的两个端点形成两条新边，构成三角形。  （4）抓这两条新边为基线，重复上述过程。直到两条新边扩展完成。  （5）重复上述过程，依次循环处理所有新边。直到所有离散点均成为TIN的端点。

说明：  SIFT特征点的提取和匹配，SIFT算法首先在尺度空间上进行关键点检测，确定关键点的位置和关键点所处的尺度，然后使用关键点邻域梯度的主方向作为该点的方向特征，最后由关键点邻域梯度信息生成关键点的特征向量(SIFT algorithm firstly detects the key points in the scale space, determines the location of the key points and the scale of the key points, then uses the main direction of the key point neighborhood gradient as the direction feature of the point, and finally generates the feature vector of the key points from the key point neighborhood gradient information)

说明：  为了达到较好的隐藏效果，本文采用游程编码的方法在二值图像中隐藏信息。秘密信息嵌入时修改二值图像的游程长度，如果秘密信息为是0，则修改该游程长度为偶数；如果秘密信息的取值与游程长度的奇偶性相匹配，则不改变游程长度。提取时根据游程长度奇偶性提取出秘密信息。在信息隐藏时，改变游程的奇偶性时通过对下一个游程的第一个像素值进行修改，因此当下一个游程长度为1时通过改变当前有成的值实现。(In order to achieve better hiding effect, we use run length encoding method to hide information in two value images. When the secret information is embedded, the length of the travel length of the two value image is modified. If the secret information is 0, the length of the travel length is even even. If the value of the secret information is matched with the parity of the length of the run, the length of the journey is not changed. The secret information is extracted according to the parity of run length. In information hiding, changing the parity of the journey is modified by the first pixel value of the next run, so the current length is 1 by changing the current value.)
