自己写的两副图像的特征点匹配，其中用了opencv类库，功能包括：特征点的亚像素精度检测，特征点初始匹配，基本矩阵计算及对极约束引导匹配等。-himself wrote the two images and matching feature points, which used the OpenCV library, features include : the feature points subpixel accuracy testing, the initial matching feat

位移约束下，利用ESO方法进行连续体结构拓扑优化-ESO method-based topology optimization of the continuous structure under the constraint of displacement

利用渐进结构法求解位移和频率混合约束下的连续体结构拓扑优化，获得材料的最优布局-use evolutionary structure method to solve the topology optimization under the constraint of displacement and frequency

对于带噪声的周期性纹理图像,提出一种基于二维秩约束的混合正则化去噪方法。该方法结合了全变分去噪理论和方法，并且利用该类图像低块秩的特性，对图像进行了低块秩约束。通过和全变分去噪方法比较可知，对于周期性纹理图像，混合正则化方法能有效地分离出噪声，并且能让图像很好地保持边缘。即使非严格的周期性纹理，该方法依然有很好的去噪效果。-For periodic texture images with noise, a new method based on two dimensional rank cons

特征提取：重点是几何特征环,交叉点,端点和变换 不错的-Feature extraction: with a focus on the geometric feature of ring, intersection, endpoints, and transform is good
