FFT
1.用Matlab产生正弦波,矩形波,以及白噪声信号,并显示各自时域波形图
2.进行FFT变换,显示各自频谱图,其中采样率,频率、数据长度自选
3.做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱
4.用IFFT傅立叶反变换恢复信号,并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display
2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data
3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map
4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

用matlab编程工具,编写具有操作界面的应用程序,通过菜单、对话框,选项框等界面控制,对算法进行演示。需要在应用系统中实现的算法及功能包括:
1、图像增强算法
(1)灰度线形变换:亮度及对比度可以调节(通过控制参数的改变,能够实时预览变化结果);
(2)直方图均衡:可在界面上对比均衡前后的效果。
2、图像变换算法
(3)对一幅彩色图像进行DCT变换和反变换,对比结果和原图;
(4)仅保留左上角16X16的DCT系数,进行反变换,计算结果图的信噪比SNR。
3、图像分割算法
(5)采用最优阈值算法对灰度图像进行分割;
(6)用Canny算法对灰度图像进行边缘检测;
(7)用hough变换,检测边缘图像中的直线,并用不同颜色将检测出的直线叠加显示到原图像上。
