一维最大熵图像分割算法的MATLAB实现源代码(the matlab code for degital image segment)

[W,L,q]=huffman(P) 为huffman编码函数 P为信源的概率矢量，W为编码返回的码字 L为编码返回的平均码字长度，q为编码效率 ">

该matlab程序实现字母T和L的区分，在9*9格形框里，字母T和L有不同的位置，任意位置，神经网络都可以识别出是T还是L(The program matlab and distinguish letters L, T, in the grid-shaped box 9* 9, the letters L and T have different locations anywhere in the neural network can identify a T or L)

DTMB，全称Digital Television Terrestrial Multimedia Broadcasting(Digital Television Terrestrial Multimedia Broadcasting)

使用matlab仿真随机编码过程，可以成功运行(To use matlab simulation of random coding process can be run successfully)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)
