Abstract:
This paper proposes a structure and texture similar image matching method based on improved SIFT algorithm in order to solve the problem that SIFT features matching algorithm exist many errors because it rely heavily on gray information,which would lead to non-ideal effect of stitching.We make use of color information and spatial information to filter the matching point-pairs,so as to achieves better accuracy and overcomes the traditional SIFT algorithms disadvantage.Experiments show that the proposed algorithm improved the robustness and the effect of stitching.
