代码说明:

抽象 — — 方法已广泛应用于图像的设置级别 处理与计算机视觉。在常规水平设置配方, 水平集的函数通常开发期间违规行为 其演变,这可能会导致数值错误并最终摧毁 演变的稳定性。因此,数值的补救办法, 被称为重新初始化,通常应用于以定期更换 退化的级别设置符号的距离函数的函数。 但是,重新初始化的做法不仅引起严重 问题时,它应如何执行,而且还会影响 不可取的方式的数值精度。本文提出的 新的变分级别设置制定在其中的规律 水平集的函数本质上被维护期间水平 设置的演变。水平集的演化派生作为渐变流 尽量减少能源功能与距离经常化 期限和外部能源驱动的零个议案

    基于matlab的OFDM仿真程序; 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

  • code_v1-0
    This program illustrates the Fuzzy c-means segmentation of an image. This program converts an input image into two segments using Fuzzy k-means algorithm. The output is stored as fuzzysegmented.jpg in the current directory. This program can be generalised to get n segments an image by means of slightly modifying the given code.

    介绍了构造均匀设计表的好格子点算法与生成原理,以中心化偏差为均匀性测度,使用MATLAB编写了生成中心化偏差值最小的均匀设计表的计算机通用程序,通过与文献比较,验证了程序的正确性,得到了更多的均匀设计表(The principle and good lattice points designing uniform design table are introduced,the general MATLAB programs for uniform design table are proposed base on searching the minimum of uniform design table s centered L2-discrepancy. The results shows that the programs are right by comparison of the others.)
