The pixel-level anti-diffusion method and its application in corresponding points matching

摘要

Texture enhancement is extremely important for image analysis. In this paper, a pixel-level texture enhancement method based on heat conduction equation is proposed. Using this texture enhancement method can efficiently enhance the hidden texture which would increase matching accuracy. And the existence and uniqueness theorem of corresponding points matching(CPM) are also given, the paper proposes pixel-level texture enhancement method based on heat diffusion principle The experiment shows that when the texture contrast and hidden texture visibility increases, the feature points have no moving by using this proposed method, which can be also an advantage. In addition, the proposed method improves the distinction between local texture, meanwhile, increases the quantity of the corresponding points(CPs) of the matching.
