基于混沌置乱的DCT域灰度级盲水印算法 需要的可以看下~(Based on Chaotic Scrambling DCT-domain blind watermarking algorithm for gray-level needs can facie ~)

计算一幅图像的熵，matlab编程文件，任意读取一幅图像，计算信息熵(Calculate the entropy of an image)

这个事关于Computer Graphics （计算机图形学）的教学代码！！！(The thing about Computer Graphics (computer graphics) teaching the code! ! !)

说明：  基于mean-shift运动目标跟踪matlab源代码(Based on mean-shift object tracking matlab source code)

Guilde Filter 图像滤波； 包含[2015]Fast Guilded filter.pdf ; [2013] Guided Image Filtering.pdf 经典。(inculde classical paper for guilded filter)

利用分数阶傅里叶变换的方法，通过迭代相位将加密图像替换为所需要的相位达到加密效果，上传压缩包包括代码和图片，不需要任何修改即可运行。(Using a fractional Fourier transform, the iterative phase replaces the encrypted image with the required phase to achieve the encryption effect. Uploading the compressed package includes the code and picture, and it can be operated without any modification.)

本例功能是显示一个由反走样处理的线段组成的八面体(functions of the cases showed an anti-aliasing by the Line of octahedral)

此函数三维可视化显示太阳，地球和月亮。可以输入现实参数数据(Function SSEM displays 3D Visualization of SUN, EARTH and Moon with two option i.e. with actual data and without actual data just for fun.)

产生正弦信号，加入高斯白噪声，并用小波方法去噪(Produce sine signals, add white gaussian noise, and wavelet denoising method )
