A RANSAC image mosaic algorithm with preprocessing
Chenyu Xu · Electronic Design Engineering · 2013
In view of the problem that the excessive iterations lead to higher computational complexity,and the lower accuracy result in the bad effect of mosaic.In this paper,a RANSAC image stitching algorithm with preprocessing is proposed to solve above shortcomings.This algorithm includes: image feature extraction and matching,preprocessing,generating transformation matrix,image registration and image fusion.The novelty of this paper is filtering data set by topology map with Delaunay triangulation,and choosing the RANSAC algorithm initial points by the Euclidean distance.The flowchart and Matlab-based programming were designed.Comparing with the original algorithm,the experimental results show that this method has lower computational complexity and can improve the mosaic efficiently.
