图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)

演示椭圆的曲率圆的动画。该程序演示了椭圆各点的曲率变化及相应的曲率圆圆心的轨迹。(Demonstration of the curvature ellipse circle animation. The program demonstrates the various points of the curvature of the ellipse and the corresponding changes in the curvature of the round locus of the center.)

说明：  内容：运用PM算法识别空间目标。程序中附有注释，可改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: The use of PM space target recognition algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

LM算法的MATLAB实现。Levenberg-Marquardt算法是最优化算法中的一种。最优化是寻找使得函数值最小的参数向量。(LM algorithm in MATLAB. Levenberg-Marquardt algorithm is an optimization algorithm. Optimization is to find the minimum value makes the function parameter vector.)
