A NOVEL REMOTE SENSING IMAGE CHANGE DETECTION ALGORITHM

Traditional remote sensing image change detection algorithm cannot simultaneously ensure high accuracy,strong anti-noise ability and low time cost.To solve this question,this paper designed a novel remote sensing image change detection algorithm based on nonsubsampled shearlet transform and adaptive pulse coupled neural network.Neighborhood information was applied to effectively reduce the number of false alarms,and we used multi-directional and multi-scale decomposition of nonsubsampled shearlet transform and global and local filtering to effectively reduce the number of missed alarms.The nonsubsampled shearlet transform had the invariance of translation,rotation and scale,which effectively improved the anti-noise ability.The classification accuracy of the adaptive pulse coupled neural network was high and the time cost was low.The experimental results show that compared with the other algorithm,the algorithm has higher detection accuracy for OE,PCC,KC,Recall and F1 performance indicators.It has stronger anti-noise ability and lower time cost.The experimental results fully prove the superiority and feasibility of the algorithm.
