令x(n)=5exp(j*0.15*n*n)+6exp(j*300n-j*0.15*n*n) ,w(n)为高斯窗函数。试用matlab软件,取不同长度的窗函数,分别求x(n)离散短时傅里叶变换,并进行信号重构。(ORDER x (n) = 5exp (j* 0.15* n* n)+6exp (j* 300n-j* 0.15* n* n), w (n) for the Gaussian window function. Trial Matlab software, take different lengths of the window function x (n), respectively, seek to discrete short-time Fourier transform, and to reconstruct the signal.)

绣花问题是连续型的填充,在不同区域的缝制过程中,缝针不能提针,因此不能用一般的离散型区
域填充方法处理。本文运用几何计算和图论理论提出了一个绣花缝针轨迹自动生成算法:先对轮廓走向进行
定义,通过轮廓铅垂方向的局部极值点的分割线将图案从上向下进行分割,采用交点的特征值比较彻底的解
决了分割时的重点问题,将图案区域准确的划分成缝针能一次完成的若干个节点。在此基础上根据节点的邻
接关系建立节点的邻接“图”,通过图论中半哈密尔顿路径或深度遍历方法找到节点的遍历(缝制)序列和每
个节点的缝制方向,最后可对设定的起点、终点和缝针间隔的条件自动提供缝针的走向轨迹。(In the process of embroidering, needle can not hang up for changing to a different area. Therefore, Embroider
problem could be abstract as a continuous area-filling work. Considering disperse area-filling methods can not process this
problem well. Based on geometry computing and graph theory, an algorithm of finding path of embroidering needle are
proposed in this paper. First, outline orientations are defined, and finding all local extreme points of inner outline on their
gravitational orientation to build sectioning lines so as to divide the picture. By using intersection point character the
overlap point problem was solved perfectly. Therefore, the picture is divided into some nodes which can be finished alone.
Then, based on connections of these nodes, an adjacency graph of nodes was built. Using half-Hamilton path or depth-first
search method, both embroidering sequence and direction of these nodes could be got from the graph. Finally, from a
defined start-point, end-point)

自写M函数,做灰度图像的灰度级数及灰度范围的自定义设置。例如:将[0 255]的uint8图像变换成8级灰度的灰度范围为[0 7]图像或者[11.5 25.8]图像。
输出图像为double类,用户可将图像归一化后自行转换为所需类型。(This is a M function written by self, it can be used to rebuild a image with a given number of gray-level and a given gray-scale.
Output image is double class.)
