基于dwt的数字图像水印技术的matlab源代码。包括嵌入和提取，效果不错。(Dwt-based digital image watermarking technique matlab source code. Including the embedding and extraction, good results.)

采用canny算子加上lee滤波器对SAR图像进行去噪(canny algorithm and lee filter to aiti-noise SAR image)

自适应多尺度复合形态滤波，对信号或图像实现滤波(Adaptive Multi-scale Compound Morphology Filter)

用freeman链码 来提取图像特征 以便识别(Freeman chain code used to extract the image feature to identify)

说明：  利用稀疏矩阵思想进行图像的超分辨率重建，效果较好。(Thinking of using sparse matrix for image super-resolution reconstruction, the effect is better.)

拉普拉斯变换是工程数学中常用的一种积分变换，又名拉氏转换。拉氏变换是一个线性变换，可将一个有引数实数t（t≥ 0）的函数转换为一个引数为复数s的函数。(Laplace transform is a commonly used engineering mathematics integral transformation, also known as Laplace Transform. Laplace transform is a linear transform, argument can be a real number t (t ≥ 0) is converted to a function of a complex number s argument of the function.)

实现图像的方差，斜度，峰度，能量和熵的实现，代码简单，可以直接运行(matlab graph variance)

基于Matlab的函数优化遗传算法程序,包含了遗传算法实现的大部分步骤(Based on Matlab function optimization of genetic algorithm, contains most of the genetic algorithm implementation steps)

GABOR对SAR图像进行滤波及纹理提取，可直接使用(GABOR of SAR image filtering and texture, can be used directly)
