AM FM PM matlab codes

用matlab实现lagrange和Newton插值方法(Achieved with matlab lagrange interpolation and Newton)

对图像进行算数平均滤波，希望对大家能有所帮助。(The image, and I hope to average filtering arithmetic we can help. )

二维离散小波变换(Mallat快速算法)对图像进行二维离散小波变换, 变换级数大于等于3级,然后进行阈值化处理(阈值约为10左右),再统计系数中0的个数（百分比表示）并进行重构, 最后计算重构图像的峰值信噪比(PSNR). 数据：灰度图像lena.bmp或其它图像, 滤波器系数可以调用matlab中的wfilters函数获得, wfilters函数的使用请在matlab中help wfilters.(Two-dimensional discrete wavelet transform (Mallat fast algorithm) two-dimensional discrete wavelet transform image transformed series is greater than or equal to 3, and then processing thresholding (threshold of about 10 or so), the number of re statistical coefficient 0 ( reconstruct the final calculation of the peak signal-to-noise ratio (PSNR) of the reconstructed image data: the grayscale image lena.bmp or other images, the filter coefficients can call matlab in wfilters function to obtain, wfilters function, expressed as a percentage) in matlab help wfilters.)

Matlab的编程指南(下册),常用的Matlab入门教程,比较详细非常好用的哈!(Matlab programming guide, commonly used Matlab Tutorial, detail very easy to use Ha!)

利用混沌系统给图像加密，加密方法简单易懂，对初学者很好理解(Image encryption using chaotic systems ，encryption method is simple and easy to understand, good for beginners to understand)
