project11-02
- 本实验要求编写课本上11.2.3节描述的傅立叶描绘方法。用实验09-02中的程序提取图12.18两幅图的边界,然后对每个边界选取256个描述点。选择的这256个点是在空间上尽可能均匀的点。获取每个图的傅立叶描绘子,确保每个图中的起始点是近似相同的点。分别用16,32,64和128个描绘系数逼近边界,并画出每一个结果。-Prepared at the request of the experimental section 11.2.3 textbook depicts Fourier method
TwoDimensionalFastFourierTransform
- 本实验要求开发一个2-D FFT程序包,使其可以应用于后续的几个实验。这个程序需要完成的功能是用因子(-1)^(x+y)乘以输入图像以实现滤波的中心变换,并还要求用一个实矩阵乘以一个复数矩阵通过调用两个图像的乘法程序来实现对应元素的相乘,同时计算反傅立叶变换,得到的结果乘以(-1)^(x+y)并取其实部最后计算频谱。实验中用到傅立叶变换的基本公式,通过实验我们可以更加深刻的理解频域滤波的基础。-The experiment calls for the development of a 2-D F
