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 described. 09-02 with the experimental procedures in Figure 2 Extraction of Figure 12.18 the border, and then select the border of each descr iption of 256 points. This choice is the 256 as far as possible in the space of the points evenly. Access to each of the Fourier descr iptor map to ensure that each figure is the approximate starting point for the same point. 16,32,64, respectively, and coefficient of close to 128 described the border, and the results of each draw.
