遥感图像目标的定位算法
Location Algorithm of the Target in Remote Sensing Image
摘要
Abstract
In order to locate the target in the remote sensing image fast and accurately, a credible target location algorithm is proposed: After the reference image determined and remote sensing image preprocessed, the wavelet decomposition of the two images was completed firstly. Then a SIFT algorithm was used to detect spots and wavelet coefficients of high-frequency energy to detect corner points. Further, two types of characteristics were described by SIFT feature descriptor and matched by adding direction constraints. When two transformation models were obtained, their similarity was judged in order to ensure the reliability of the registration result. If the result was reliable, then the target was located in the reference image. Finally, the experimental results show good real-time performance, reliability and feasibility of the algorithm.关键词
