三维曲线曲面比较演示系统程序设计 设计一个图形用户界面（GUI）演示常见的三维函数图形，至少包含“三维绘图” 、“选项” 、“退出”等菜单，三维绘图的包括：参数方程x=e-t/20cos(t), y= e-t/20sin(t),z=t其中t 为0到2π、参数方程x=t,y=t2,z=t3其中t为0到1之间（在同一图形界面中分别绘制它们的三维曲面和三维曲线图）。“选项”菜单主要包括：网格开关，图例开关，坐标边框开关，色度空间选择菜单，曲线颜色菜单。(Comparison of three-dimensional curves and surfaces demonstration system design to design a graphical user interface (GUI) presentation function common three-dimensional graphics, at least three-dimensional graphics, options , Exit menu, etc., three-dimensional graphics, including: parameters of equation x = et/20cos (t), y = et/20sin (t), z = t one of t from 0 to 2π, parametric equation x = t, y = t2, z = t3 which t is between 0-1 (in the same graphical interface, respectively, three-dimensional mapping of their surface and three-dimensional curves). Options menu includes: grid switches, legend switches, coordinate frame switch, color space selection menu, menu color curve.)

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(The matlab program to achieve the target object' s image segmentation and extraction technology, in the annex of the procedures for license plate detection and recognition, for example, the effect was very good.)

设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)
