- Envelop of Error Model of 2 D Spatial Curve in GIS
GIS中平面一般曲线误差模型包络线 - HHT has not been put forward for long time, so it contains some theoretical problems, such as envelop and mean curve fit, boundary effect, modes mix and so on.
HHT刚提出不久，其理论本身还存在不少问题，如包络线和均值曲线的拟合、边界效应和模态混叠等问题。 - At last, the optimum threshold was calculated by watershed algorithm according to the envelop curve and then CR image was segmented quickly by calculated threshold that presents the feature of image.
最后根据从直方图中提取出的、代表图像特征的阈值对CR图像进行实时快速分割，在采集完图像的同时就可以得出分割结果。 - This paper presents a new scheme of authentication, digital signature and digital envelop based on elliptic curve cryptosystem which replaces RSA algorithm. It is proved that the scheme greatly improves the security, performance and speed of internet transaction.
设计了一种基于椭圆曲线密码体制的认证、加密和签名方案，以代替RSA算法，使网络交易的安全性、性能和速度获得显著的提高。 - According to the concept of envelop evaluates equation Come to the conclusion that the projection of torus is close elliptic equidistant curve but is not ellipse.
根据包络的概念解出轮廓线的方程式。从而得出结论：圆环面的轮廓线是封闭的椭圆等距曲线，而不是椭圆。 - First, the histogram of image was calculated, and then the histogram was filtered by mathematical morphology to extract the envelop curve.
首先计算出图像的直方图，然后对直方图进行形态学滤波，提取出直方图的包络。
