基于分数阶变换和改进最小生成树的图像配准算法
Image Registration Algorithm Based on Fractional Order Transformation and Improved Minimum Spanning Tree
摘要
Abstract
In order to improve the accuracy and stability of image registration,a new robust image registration algorithm is proposed in this paper.The Fractional Order Transformation(FOT) is defined to enhance the characteristic information of the image.And the image signal is transformed into the scale space by combining the fractional order and Gauss kernel function,then the image feature points are extracted by scale-invariant feature transform.The Minimum Spanning Tree (MST) is improved to establish the structure relation of feature points for finishing the feature points matching.The random sample consensus algorithm is introduced to reduce mismatching.Experimental results show that this algorithm has higher registration accuracy and robustness compared with the current image registration algorithm based on Harris corners,k-d trees and blocks.关键词
