Intensity inhomogeneity refers to the smooth intensity change inside the originally homogeneous regions. Filter-based inhomogeneity correction methods have been commonly used in literature. In this paper, a new filter-based inhomogeneity correction method is proposed based on fourth order complex diffusion. The effectiveness of the proposed method is compared with other filter-based Inhomogeneity correction methods. The results demonstrate that the proposed method outperforms the other methods in terms of coefficient of variation and coefficient of joint variation.
