完整的可运行AAM模型的matlab代码，附有测试图像，matlab 2009测试通过(Complete AAM model can run matlab code, with a test image, matlab 2009 test pass)

这是数字水印嵌入程序,一共有三个,希望对大家有用.图片一定要用灰度图片.(This is a digital watermark embedding process, a total of three, in the hope that useful to everyone. Picture must use gray picture.)

说明：  提取纹理图像特征，包括平均值、标准差、平滑度、三阶矩、一致性、和熵。(Extract texture features, including mean, standard deviation, smoothness, third moment, consistency, and entropy.)

基于sift算法的图像拼接matlab代码，经过测试，可以运行，对有重叠部分的图像进行拼接，效果不错(Sift algorithm based on the image mosaic matlab code, the test run splicing with overlapping portion of the image, good results)

利用基于直方图的自适应阈值方法实现分割前景与背景(The use of foreground and background to achieve segmentation adaptive threshold method based on histogram)

相位恢复算法,利用恢复图像在时域必须是正实值以及正逆傅里叶变换进行恢复(phase retrieve)

说明：  SAR回拨模拟及CS算法成像，参考书：合成孔径雷达成像原理（皮亦鸣）(CS algorithm for SAR call-back simulation and imaging, reference books: Synthetic aperture radar imaging principle (PI Yi-ming))

说明：  图像高斯滤波,再边缘检测中,首先要用到高斯滤波(images Gaussian filtering, edge detection again, the first use of the Gaussian filter! !)

最大熵多阈值实现多红外图像的实时处理，多阈值实现(The maximum entropy multi-threshold to achieve real-time processing of multiple infrared image.)

this codes describe several kind of image filters
