用改进欧拉法求解常微分方程初值问题：用改进的欧拉法不仅提高了精度而且算法比较简单，(The improved Euler method to solve initial value problems of ordinary differential equations: Euler' s method with improved accuracy and the algorithm not only improve relatively simple,)

采用PCA提取人脸特征,先计算M个图像的平均值脸，再求出各特征值脸。(Using PCA for face feature extraction, first calculate the average face image of M, and then find the face value of each characteristic.)

说明：  自编的粒子群聚类的算法通过改进可以正常的进行点的筛选(Particle clusters self class of algorithms can be normal by improving the screening for point)

提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)
