Description: 在心电信号处理过程中，为了避免产生Gibbs 振荡现象和严重的频率混叠现象，提出一种基于双树复小波变换，并结合最大后验估计确定阈值的心电信号去噪方法。文中采用了信噪比和均方误差来评价双树复小波变换和离散小波变换两种方法对心电信号的去噪效果。实验结果表明: 与传统离散小波变换相比，双树复小波变换去噪更彻底，边界、纹理等特征能较好地保留，可以作为一种生物医学信号降噪处理的新方法。-In ECG signal processing， in order to avoid the phenomena of Gibbs oscillation and severe frequency aliasing，a new ECG signal denoising algorithm is presented，which is based on dual-tree complex wavelet transform and combined with the maximum a posteriori estimation to determine the threshold． The signal-to-noise ratio and mean square error are used to uate the denoising effects of the dual-tree complex wavelet transform and discrete wavelet transform． The experimental result shows that compared with traditional discrete wavelet transform， the dual-tree complex wavelet transform reduces noise more thoroughly and retains boundary and texture characteristics better． The dualtree complex wavelet transform can be used as a new denoising method for biomedical signal denoising processing．

Description: 对连续时间正弦信号x(t) sin(2π t+ )，可以按抽样频率 1/ 对x(t)抽样来获得离散时间信号x[n] x(t) sin( ).
以不同的组合f0和fs绘出x[n],可以说明混叠问题。以下，去抽样频率fs 8kHZ.
(a)绘出一个被抽样的正弦波单图。正弦波频率300Hz，10ms间隔上抽样，相位任意指定。使用stem绘图。
(b)使用plot绘图。
(c)将正弦波频率从100Hz变至475Hz，每次增加125Hz。绘图。
(d)将正弦波频率从7525Hz变至7900Hz，每次增加125Hz。绘图。
(e)将正弦波频率从32100Hz变至32475Hz，每次增加125Hz。绘图。
讨论显现频率是增加还是减少
-For the continuous time sinusoidal signal x (t) sin (2π t+), the discrete time signal x [n] x (t) sin () can be obtained by sampling the sampling frequency 1/x (t).
The x [n] is plotted with different combinations f0 and fs, which can explain the aliasing problem. Here, the sampling frequency fs 8kHZ.
(A) Draw a sampled sine wave single graph. Sine wave frequency 300Hz, 10ms interval sampling, the phase specified arbitrarily. Use stem drawing.
(B) use the plot plot.
(C) change the sine wave frequency 100Hz to 475Hz, each increase 125Hz. Drawing.
(D) change the sine wave frequency 7525Hz to 7900Hz, each increase 125Hz. Drawing.
(E) change the sine wave frequency 32100Hz to 32475Hz, each increase 125Hz. Drawing.
Discuss whether the apparent frequency is increased or decreased

Description: 根据OpenGL提供的直线，多边形绘制算法（橡皮筋效果），实现基于鼠标交互的卡通人物设计与绘制。使用颜色填充与反走样技术对卡通人物外貌以及衣着进行绘制。实现对卡通人物轮廓的交互控制，点击鼠标左键可以对人物五官位置进行拖拽移动调整。按“↑”按键能够实现卡通人物绕坐标原点（或指定点）进行旋转。
附加要求：选中其中的一个多边形区域，点击鼠标右键，弹出一个菜单，可以对该区域进行不同颜色的选择。可以设计发型、衣服的模版，当作文件进行存储，可以在窗口最右边设计一个模板库，显示保存的发型与衣服，拖拽到卡通人物上可以为卡通人物进行发型或者衣服的替换。
-According to OpenGL provides a straight line, polygon rendering algorithm (rubber band effect), based on the mouse interaction cartoon character design and rendering. Use color fill and anti-aliasing techniques to draw cartoon characters and dress. To achieve the cartoon character contours of the interactive control, click the left mouse button on the character position can be drag and move to adjust. Press the ↑ button to achieve the cartoon characters around the coordinates of the origin (or designated point) to rotate.
Additional requirements: one of the polygon area, click the right mouse button, pop up a menu, you can choose the different colors of the region. You can design the hair, clothes, templates, as a file for storage, you can design the right side of the window template library, showing the saved hair and clothes, drag the cartoon characters can be cartoon characters for hair or clothes replacement.
