图像处理

1)编写DFT子函数（计算并画出幅频特性），以后可调用。 2）N=32，M=32，128，256时，分析频率分辨率、频谱的光滑程度。 3）N=64，256，512时，分析频率分辨率和频谱的光滑程度。 -1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.

制作火焰文字 运行时文字周围有火焰闪动，颇为好看。 基本思想： 对于给定的文字，其周围的三原色分量值往外依次减去一个随机量 （该随机量随时间改变，造成动画效果），直到减到0为止。在文 字周围即可看到比文字颜色淡的火焰。如果忽略蓝色分量，并使黄 色分量减的快一些，即可得到真实的火焰效果。 -text characters running around a flame flicker, rather pretty. Basic idea : For a given language, around magenta-money overseas minus a random order quantity (the amount of random change with the times. create animation effects), until reduced to 0 so far. In the text can be seen around the text color than the desalination of flame. If neglected blue, yellow-minus enable the faster, can be real flame effect.
