wavelet transforms in advanced forms

说明：  通过高斯函数导数检测图像边缘，实质是方向可调小波变换检测图像边缘（8个方向变换）。(Gaussian function through derivative edge detection in real terms is adjustable direction edge detection wavelet transform (change the direction of 8).)

说明：  基于dct系数的数字水印算法实现，在matlab环境中实现(coefficient based on digital watermarking algorithm in Matlab environment to achieve)

使用小波变换的图像边缘检测算法(use wavelet transform Edge Detection Algorithm)

基于四阶累积量的矩阵方程法子波估计,对研究子波的有一定的帮助(based on the forth cumulantion seismic wavelet estimation)

离散小波变换的简单程序，适合初学者学习，附有通用函数。(Simple procedures discrete wavelet transform, suitable for beginners to learn, with common functions.)

基于小波变换的码元速率估计，估计精度很高。还有测试信号和mpsk函数功能。(Symbol rate based on wavelet estimation, estimation accuracy is high. There are test signals and mpsk Function.)

此程序用DWT(离散小波变换)实现二维小波变换(discrete wavelet transform )
