对图像进行基于SIFT算法的特征提取并对图像特征并实现特征匹配(the implement of the sift algorithm and matching based on the feature extracted the image)

这是一个matlab与simulink模型交互的例子，希望对大家有帮助。(This is a matlab simulink model of interaction with the example, we want to help.)

非线性动力学系统荙芬方程matlab-simulink仿真分析(The Da Fen equations of nonlinear dynamical systems matlab-simulink simulation analysis)

基于MATLAB平台的产生随机正交矩阵的函数，非常好(a numerical algorithm for generating a random symplectic orthogonal matrix )

说明：  利用Matlab软件平台对JTC进行了图像识别仿真实验，得到了二维及三维相关输出图像，显示出尖锐的相关峰。仿真实验表明：联合变换进行图像识别中存在强烈的零级干扰，干扰信号是有用信号的7.14倍，输出结果不理想；采用功率谱相减法可以消除零级强干扰，进而提高了图像的识别能力。(Simulations of joint transform correlator (JTC) using Matlab is implemented, and the 2-D and 3-D drawings of the correlation image are obtained. In the simulation experiments, the sharper correlation peaks are showed. The result shows that strong disturbance of zero rank exists in the simulation of JTC, and it is 7.14 times stronger than the useful signal thus, the power spectrum subtraction is used to eliminate the strong disturbance, and the capacity of image recognition is improved.)
