Abstract

In this paper

the robustness problem in medical image registration algorithm based on mutual information is analyzed.A new method is proposed

which establishes image fuzzy gradient field and sets up the measurement of fuzzy gradient similarity.Then it is combined into the algorithm based on mutual information.Our experiments illustrate that this method can efficiently solve the robustness problem in the traditional algorithm based on mutual information and match medical images quickly and stably.
