[Other] Improved-SIFT-feature DL : 0: 由于成像条件变化造成的遥感图像之间的几何形变和灰度差异给影像匹配带来了困难，深入研究了 SIFT特征描述符的生成方法，针对SIFT特征维数过高的问题进行改进，利用特征点邻域的圆形区域构造新的描述符，增强了描述符自身的抗旋转性，并降低了特征描述符的维数。实验表明，改进的特征描述符是可行有效的，在遥感影像目标匹配中取得满意的实验结果。-Remote sensing image geometric distortion caused by changes due to imaging conditions and grayscale differences between makes it difficult to image matching, in-depth study SIFT feature description generation method breaks, improved SIFT features for the problem of high dimensionality, feature points using a circular neighborhood new regional structure Descriptor, the descriptor itself enhances the anti-rotation resistance, and reduces the number of dimensions of feature descriptors. Experimental results show that the improved feature descriptor is feasible Effective and achieve satisfactory results in Remote Sensing Image Matching.
