一幅彩色图像数字化后，在显示时颜色经常看起来有些不正常。这是色通道的不同敏感度，增光因子和偏移量造成的，称为三基色不平衡。这个校正过程称为彩色平衡。(After a digital color image in the display color always looks somewhat normal. This is a different color channel sensitivity factor and credit to offset caused by the imbalance as the three primary colors. This correction process is called color balance.)

说明：  基于灰度直方图的分割算法，自己写的，即求灰度直方图的分割算法，珍藏版，可实现。 ( The segmentation algorithm based on gray-level histogram ，Write your own, namely for the graylevel histogram editions of segmentation algorithm, can achieve. )

三次样条插值，比较好的MATLAB程序，也是在计算值中不可缺少的东西(cubic spline interpolation)

里面含有盲识别BCH码的长度的代码，用于matlAB子程序调试，很好用。(BCH code which contains the length of the blind identification code for matlAB subroutine debugging, very good use.)

matlab实现黄金分割法求非线性函数的极值问题，含实例(MATLAB Golden Section min)

this code can be use in interpolation of seismic data.

组合导航的程序，主要是航位推算方法的程序(Navigation procedures, mainly dead reckoning method of procedure)

主要进行OFDM调制和解调，里面有IFFT和FFT部分，自己手动写的比较实用(Mainly for OFDM modulation and demodulation with IFFT and FFT, their practical manual)

设计一个数字FIR低通滤波器，其技术指标如下： Wp=0.2pi Rp=0.25Db Ws=0.3pi As=50db 试写出MATLAB设计的源程序。(Design a digital FIR low-pass filter, the technical indicators are as follows: Wp = 0.2pi Rp = 0.25Db Ws = 0.3pi As = 50db test designed MATLAB source code to write.)

说明：  matlab 程序 是自己写的，太简单科别笑我 希望有人支持(matlab program is written in their own, too simple divisions laugh, I hope there is support for)
