image processing in matlab

The BCJR algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises (principally convolutional codes). The algorithm is named after its inventors: Bahl, Cocke, Jelinek and Raviv.[1] This algorithm is critical to modern iteratively-decoded error-correcting codes including turbo codes and low-density parity-check codes.

adrc历程，可以编译通过并使用。简单易懂，注释稍微有些少，有基础可看懂。((ADRC algorithm, easy to understand, comments somewhat less, there is a basis can be read.))

用互相关法求相对剩余静校正量；并用时差统计法或相关函数统计法分离，最后可求出记录道的绝对剩余静校正量。(Using cross correlation method the relative residual statics and separated by the difference method or statistical correlation function statistics of the last track can be obtained an absolute residual statics.)

说明：  用于图像边缘检测，使用matlab检测图像边缘特征(For image edge detection, use matlab to detect image edge features)

Newton插值公式实例，改变插值节点个数，观察不同的插值函数的逼近效果.(Instance of the Newton interpolation formula, change the number of interpolation nodes, and observe the different interpolation function approximation.)

基于遗传算法和免疫算法的的数据挖掘算法对比，用Matlab编写(Mining algorithm of genetic algorithm and immune algorithm based data, using Matlab prepared)

说明：  .m语言编写，m序列设计，walsh序列设计，最后异或成伪随机序列。 最终分析伪随机序列之间的互相关自相关(. M programming language, m sequence design, Walsh sequence design, finally xeroxor pseudo-random sequence. Finally, the correlation and autocorrelation between pseudo-random sequences are analyzed)
