algo of matlab code to find obstacle

coil20 人脸数据库，matlab格式(coil20 face database)

说明：  实现二维路径规划,包含遗传算法,rrt算法，a星(Realize two-dimensional path planning)

各种调制方式的代码，包括单天线和单天线等。(Various modulation code, including single-antenna and single antenna and so on.)

本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)

joke it s just for creating manner dont be sirious

实现（2，1，7）卷积编码以及相应的viterbi译码(achieve (2,1,7) convolutional code and the corresponding Viterbi decoding)

对原始灰度图像进行图像压缩，对此图进行 8×8 DCT 变换后，分别只保留 DC系数，以及保留前 4、8、16 个变换系数(DC＋AC) ，然后再分别进行 IDCT 变换 (The original gray image compression, this map for 8 × 8 DCT transform, respectively, to retain only the DC coefficient, and to retain the former 4,8,16 months transform coefficients (DC+ AC), and then separately IDCT transform)

该段代码可用于加速度信号的积分求得位移。使用的是频域积分方法，设置合适的上下限截止频率可较好的复现实际路面的位移高程。(This code can be used for integration of the acceleration signal obtained displacement. Using a frequency-domain integral method, set the appropriate upper and lower cutoff frequency displacement elevation better reproduce the actual road.)

说明：  本资源运用Matlab中的计算机视觉技术对视频监控中的运动人体的一些异常行为进行研究分析，涉及到了运动目标检测以及跟踪和人体异常行为检测等几个方面。背景模型的建立则是分别利用了中值滤波法和二值化背景模版建模法，通过帧间差分 来实现不断更新背景模版。在检测运动人体异常行为中，本文在检测运动人体跌倒的异常行为时利用外接矩形来确定运动人体及其质心，并通过定义一些特征算子来把人体行为进行量化，从而判断是否行为异常。(In this paper, we use matlab technology to detect abnormal human movement and video resources. The background model is established by using the median filtering method and the binary background template modeling method, through the frame difference To update the background template constantly. In the detection of abnormal behavior of moving human body, this paper uses the outer rectangle to determine the moving human body and its center of mass, and defines some characteristic operators to quantify the human behavior, so as to determine whether the abnormal behavior.)
