实现车牌定位 matlab程序 对车牌进行分割提取(License Plate Location realize matlab program to extract license plate segmentation)

在理想的信道状态条件下，对MIMO-OFDM系统进行仿真，包括信道估计，调制，解调，信道编解码等(In an ideal channel state conditions, the MIMO-OFDM system is simulated, including channel estimation, modulation, demodulation, channel coding and decoding)

说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)

自己做的一个DCDC升压电路模型，通过设置占空比可以将电压升高到目标值(DCDC boost)

本程序实现对随机信号的8PSK调制，程序里面有详细注释，很容易换成想要信号的8PSK调制，欢迎下载。(This program implements the random signal 8PSK modulation, which has detailed program notes, easily replaced want 8PSK modulation signal, welcome to download.)

针对信号分选的几种常见算法，包括pri变换，sdif（序列差直方图）算法，cdif（累积差直方图）算法，可以解决类似于固定重频信号，抖动重频信号，滑变重频信号和参差重频信号的分选等(For several common signal sorting algorithms, including pri transform, sdif (sequence difference histogram) algorithm, cdif (cumulative difference histogram) algorithm, can solve similar fixed repetition frequency signals, jitter signal repetition, repetition becomes slippery sorting and mixed signal repetition frequency signals, etc.)

粒子滤波的学习程序 简单介绍了粒子滤波的入门程序有学习价值(particle filter)

hartley计算机视觉中，利用对极几何和极线原理，求取图像之间的匹配，实现摄像机自标定，里面有对应的pdf文件原理说明(Hartley s Computer Vision in the multi-view geometry program, contact the three-dimensional reconstruction of the pole geometry and take pole lines, and camera self-calibration, which has a corresponding program and pdf files)

说明：  利用matlab将一个图片作为水印插入另一个图片，然后可以将水印再提取出来(Matlab will use a picture as a watermark inserted another picture, and then can be re-extracted watermark)
