信号与系统试验报告
离散傅立叶变换(DFT)和频谱分析
一、实验内容
1、实验题目
(1)编写DFT、IDFT程序,并验证其正确性(提示:可利用冲激函数进行验证)。
(2)计算信号f(t)=e-at2sin(2∏ft)的离散傅立叶变换(DFT),求其振幅谱,相位谱、振幅最大值对应的频谱(检测主频)以及对发f(t)进行DFT变换的结果实现IDFT变换,并画出图形。
参数选择如下:频率f =30HZ,a=f 2㏑(M),M=2.5
2、通过实验理解信号振幅谱、相位谱的物理意义,掌握DFT、IDFT算法的实现方法。()

Harris-corner
Harris采用了一种新的角点判定方法。矩阵M的两个特征向量l1和l2与矩阵M的主曲率成正比。Harris利用l1, l2来表征变化最快和最慢的两个方向.若两个都很大就是角点,一个大一个小就是边缘,两个都小就是在变化缓慢的图像区域.(Harris adopted a new method of determining the corner. Matrix M of two feature vectors l1 and l2 with the matrix M is proportional to the principal curvatures. Harris use l1, l2 to characterize changes in the fastest and slowest in two directions. If both are great that corner, a little is a big edge, both small change is slow in the image area.)
