Description: 比如有1000个.jpg，其实你对每一个jpg都是同样的处理，比如 fft2，之后要存出来一组特征，假设是10个，这样的话，最后要得到一个（1000，10）的矩阵。这种情况下就需要批处理了。
-For example there are 1000. Jpg, you do the same process for each jpg image , such as fft2, then there are a set of characteristics, assumption for 10, so the last to get a (1000,10) matrix . In this case you will do a batch。

Description: 当前信号处理中，对频谱的研究不断深入，本书中讲述如何使用快速傅里叶变化进行频谱变换，和图像相关性分析，信号处理- How to use FFT2 The note explains in detail how to apply the Matlab 2-dimensional FFT for filtering of two-dimensional signals, e.g. images. It is shown how to connect the output from fft2 to the actual Fourier transform of the signal, and in particular how transfer functions of simple filters may be coded.

Description: 在下面给出的图1中寻找小写字母a。
要求
1. 程序输入图像1，输出表征字母a大概位置的图像和字母a出现的次数；
2. 使用二维fft实现，建议自己编写二维fft函数，不使用matlab自带的fft2函数。-Given below in figure 1 in search for small letters a.
requirements
1. The input image 1, output characterization of the letters a general location image and the letters a in the frequency of
2. Use 2 d FFT realize, suggested that his writing 2 d FFT function, do not use matlab bring fft2 function.

Description: Matlab图像处理库的二维傅立叶变换，时域和频域的尺寸相同，这导致傅立叶变换运算低效，这里是一个优化后的算法的代码。-Many image processing applications require an extensive usage
of FFT2 routine (or, in the most general case, a N-dimensional
FFT) of matrices having the same dimensions. In these cases Matlab
FFT2 can result extremely inefficient.
