An inviscid model for nonrigid image registration
Yi Zhao, Justin W. L. Wan · Inverse Problems and Imaging · 2011
We propose an inviscid model for nonrigid image registration ina particle framework, and derive the corresponding nonlinear partialdifferential equations for computing the spatial transformation.Our idea is to simulate the template image as a set of free particlesmoving toward the target positions under applied forces. Our model canaccommodate both small and large deformations, with sharper edges andclear texture achieved at less computational cost. We demonstrate theperformance of our model on a variety of images including 2D and 3D,mono-modal and multi-modal images.
