eng_mat.rar是matlab实例,有的matlab安装时不带，可以下载拷到matlab的example文件夹里(eng_mat.rar is the matlab example, matlab installed some without, you can download the example Kaodao matlab folder)

负责火星的一个低轨道空间站的设计。为简化结构，该空间站由一系列密闭的立方体（airtight cubical modules ACM）组成，这些ACM曾连接在一起。困扰你的一个问题是致命的病菌也许留在火星的上层大气中。因为空间站有时需要在上层大气中飞行，所以急需在ACM的各个接触面进行额外的防护，无论是边对边还是面对面，连接是密闭的，所以没有细菌能够进入。一个ACM与另外一个ACM共享的面不需要防护。如果在每个ACM每个面上都加防护，花费巨大。因此，需要知道ACM额外防护的确切面数目(Responsible for the design of a low-orbit space station on Mars. In order to simplify the structure of the space station by a series of closed cubes (airtight cubical modules ACM) composed of these ACM had together. One problem is bothering you deadly germs might stay in the upper atmosphere of Mars. Because the station is sometimes necessary to fly in the upper atmosphere, so urgently needed in all contact surfaces of the ACM additional protection, either face to face or side-to-side, the connection is closed, so no bacteria can enter. An ACM ACM shared with another surface does not need protection. If you have added protection on each side of each ACM, costly. Therefore, the need to know the exact number of additional surface protection ACM)

实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)
