通过MATLAB 仿真实现哈夫曼编码的图片压缩(MATLAB Simulation by Huffman coding of image compression)

matlab中重要的数字图像处理技术：直方均衡化，可以看出灰度图像的灰度值分布，并且去噪。(matlab important digital image processing techniques: Histogram equalization, we can see the distribution of gray-scale image of the gray value, and the de-noising.)

说明：  EEMD将特殊幅值下的高斯白噪声引入到分解的过程，可以消除上包络和下包络之间存在的拟合误差，从而很好地避免不同尺度下IMF的模态混叠现象，(EEMD can eliminate the fitting error between the upper envelope and the lower envelope by introducing the Gaussian white noise with special amplitude into the decomposition process, so as to avoid the mode aliasing of IMF at different scales,)

最近编的一个小程序,可以供大家参考,初学者可以下来()

matlab和optisystem调试用的幅度调制程序，在optisystem里面使用matlab组件然后使用。(matlab and optisystem debugging with the amplitude modulation process, component and then use the optisystem inside Matlab.)

Fault detection method for nonlinear systems using TS fuzzy models. Application to the three tank system.

用matlab编写的cdma2000基带信号源的仿真程序,主要实现编码调制部分。。(Prepared using matlab cdma2000 baseband signal source simulation program, the main code modulation section. .)

说明：  验证滤波器传输函数的相位偏移，主要是分析高通滤波器和低通滤波器(Validation phase shift filter transfer function, primarily an analysis of high-pass filter and low pass filter)

说明：  一个最新的快速独立分量分析工具箱，很有用(The latest fast independent component analysis toolbox, useful)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
