SIFT图像配准，已测试比较好用，请大家放心使用(SIFT image registration)

数字水印程序，包括多分辨嵌入水印、提取水印程序，盲水印嵌入、提取程序，以及滤波攻击和JPEG攻击程序，PSNR和相似度计算公式（MATLAB）(digital watermarking procedures, including multiresolution embedded watermark, watermark extraction procedure, blind watermark embedding and extraction procedures, Filtering and attack and attack JPEG procedures, PSNR and the similarity calculation formula (MATLAB))

用matlab的分水岭分割法实现图像分割，基于形态学，提取边缘(Using Matlab watershed segmentation method to achieve image segmentation)

VTK读取BMP序列图片实现MC算法面绘制，并且将绘制结果保存为STL格式。(VTK read BMP image sequences to achieve MC surface rendering algorithm, and the results will be drawn saved as STL format.)

pca 特征提取的源代码，对人脸识别很有帮助，(pca feature extraction of the source code, useful for face recognition,)

该代码采用opencv环境来实现灰度投影估计电子稳像算法，能够很好地解决视频序列抖动问题。(The code uses the opencv environment to achieve the gray projection algorithm, which can solve the problem of video sequence jitter.)

修改过的pca-sift程序 可以正常运行(Modified pca-sift program runs)

图像的高斯与拉普拉斯金字塔分解，两种方法都有(Image gaussian and Laplacian pyramid decomposition, there has two kinds of method)
