125 Image Matching Based on Partial Differential Equations Methods

The suitable measures is discussed for the multimodal registration problem, and two approaches is presented by using different distance metrics. To minimize the distance functionals whose corresponding Euler-Lagrange equations are a coupled system of linear PDEs, an iterative method, which can be regarded as an explicit discretization of a classical gradient flow method, is put forward. Furthermore, an experimental results for a synthetic example is presented.
