用VC编写的圆弧样条，B样条曲线的绘制程序，在单文档中输入任意点，绘制出点间的圆弧样条曲线与B样条曲线-VC prepared by the arc-like, B-spline curve mapping procedures in a single document input arbitrary point and draw points of the circular spline curves and B-spline curves

数字图像处理的实验 DCT IDCT变换 灰度变换 锐化-Digital image processing experiments DCT IDCT transform gray-scale transformation sharpening, etc.

数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）水印嵌入过程为：数字水印（X）、原图像（I）和密钥/公钥（K）通过数字水印嵌入算法形成嵌入水印后的图像（I*）。 （2）水印检测过程为：数字水印（X）、水印图像（I*）和密钥/公钥（K）通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!

无线网络的通信模型建立使用 TCL 脚本。Tcl 脚本的执行与记录在它的所有模拟事件生成的跟踪文件。吞吐量的计算使用 awk 脚本进程跟踪文件并生成带有.xg 扩展名的文件中的结果。Xgraph 为吞吐量是使用所得的 awk 脚本执行的结果 （.xg 文件） 绘制的。

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.-Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.
