一个用于识别客车、轿车、面包车等的车型识别的程序，用matlab编写，利用背景差分得到车辆区域，再做后续图像处理(A model identification procedures used to identify buses, cars, vans, etc., using matlab prepared using the context of the differential area of ​ ​ the vehicle, then a subsequent image processing)

说明：  基于MATLAB的pcm编码系统的仿真系统，是用simulink搭建的。 (pcm encoder basic on MATLAB~ )

the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolutionspectral estimation of target reflectivity.all seven (7)files should be downloaded for the simulation to work.(dls3D.m,estimate.m,get2S1Data.m,getConstraints.m, getImageData.m,getPixelData.m, getSLICYData.m)

这是一个BPSK调制和产生噪声的一段程序，顺有仿真结果。(This is a BPSK modulation and noise section of the procedure, Shun has simulation results.)

这是我收藏的可以使用的灰度共生矩阵特征提取的源码，希望对大家有用(here is the code which helps to calculate the features the different GLCMs.Hope it is useful to you )

标准的卡尔曼与扩展卡尔曼滤波模板，可以直接套用。(kalman and extended kalman filter can be directly applied. )

在采样点之间的频率响应是由各采样点的加权内插函数叠加而形成的，因而有一定的逼近误差。该误差大小取决于理想频率响应的形状，理想频响特性变化越平缓，内插值越接近理想值，逼近误差越小；反之，如果采样点之间的理想频响特性变化越陡，则内插值与理想值之间的误差越大，因而在理想滤波器不连续点的两边，就会产生尖峰，而在通带和阻带就会产生波纹。用频率采样法设计的实际滤波器频率响应如图1所示。由图1可知，实际滤波器的阻带衰减取决于内插函数第一旁瓣幅度值的大小，其大小决定了所设计的滤波器的阻带性能。(Interpolation function superimposed between sampling points of the frequency response is weighted within each sampling point and the formation of, and thus have a certain degree of approximation error. The size of this error depends on the shape of the ideal frequency response and the ideal frequency response characteristic change is more gentle, interpolated and more close to the ideal value, the smaller the approximation errors Conversely, if the sampling point between the ideal frequency response characteristics of the steeper the change, and then the interpolated the larger the error between the ideal value, and thus in the ideal filter both sides of the discontinuity point, will produce spikes occurs ripple in the passband and stopband. Actual design frequency sampling filter frequency response is shown in Figure 1. Figure 1 shows, the actual filter stopband attenuation depending on the interpolation value of the size of the first side-lobe amplitude of the function that determin)
