VQ-block-size

说明：  读取视频文件，读取一帧图像并检测图像中的汽车，使用循环逐帧对图像进行检测(read the videofrequency documents,then detect the cars in the picture,use the cycle to detect the picture.)

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)

filter design by matlab

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)

免疫算法，与遗传算法相似，只是多用了一个免疫函数；免疫算法是遗传算法的变体，它不用杂交，而是采用注入疫苗的方法。(Immune algorithm, similar to the genetic algorithm, but the use of an immune function; immune algorithm is a variant of genetic algorithms, it does not hybrid, but the use of vaccination method.)
