MATLAB中证图像缩放、旋转等对Hu矩和Zernike矩的影响(MATLAB in the card image scaling, and rotation of the Hu moments and Zernike moments of)

两机五节点的仿真 可能有点错误 嘿嘿潮流分析的计算(Two five-node machine simulation may be a bit wrong hehe trend analysis calculations)

仿真对象如下： 其中， v( k )为服从N (0,1) 分布的白噪声。输入信号u ( k) 采用M 序列，幅度为 1。M 序列由 9 级移位寄存器产生，x(i)=x(i-4)⊕x(i-9)。 选择如下辨识模型： 加权阵取Λ = I。 衰减因子β = 0.98，数据长度 L = 402。 辨识结果与理论值比较，基本相同。辨识结果可信 (he simulation object is as follows: among them, v (k) to obey N (0, 1) distribution of white noise. The input signal u (k) using M sequence, amplitude is 1. M sequence by 9 level shift register generation, x (I) = x (I- 4) ⊕ x (I- 9). Choose the identification model: weighted array take Λ = I. Attenuation factor β = 0.98, the data length L = 402. Identify the theoretical calculation and comparison, basically the same. Identification results are reliable)

能量熵的计算，包含特征值与特征向量的提取、训练样本以及最后的识别，含噪脉冲信号进行相关检测,有循环检测，周期性检测，IDW距离反比加权方法，在matlab环境中自动识别连通区域的大小。( Energy entropy calculation, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Noisy pulse correlation detection signal, There are cycle detection, periodic testing, IDW inverse distance weighting method, Automatic identification in the matlab environment the size of the connected area.)

AMI码的功率谱,通过仿真产生AMI码并且绘制其功率谱图。(AMI code power spectrum, generated by simulation AMI code and mapping of its power spectrum.)

Huffman Coding Algo designed by one of my friends

使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)
