基于拓扑结构的图像拼接算法
An Image Mosaic Algorithm Based on Topological Structure
摘要
Abstract
In view of the disadvantages of low accuracy and large amount of calculation of Speed-Up Robust Features(SURF) algorithm because of too much matching feature points,according to the network topology theory,this paper proposes an image mosaic algorithm based on topological structure.This algorithm defines connectivity matrix and adopts it to eliminate error matching points and poor matching points.Through exclusive-OR operation of the two matrices,the judgment matrix is obtained.After several iterative operations,the final feature point set is generated.By calculating the transformation matrix,the image mosaic is finished.The experiment result shows that the mosaic algorithm based on topological structure can improve the accuracy of matching feature points more than 28.28%.For small resolution images,time-consuming remains unchanged,but for large resolution images,time consumption is significantly reduced.关键词
