MCIR: A Multi-modal Image Registration Algorithm Based on Membrane Computing

In order to realize the rapid and exact image registration, a multi-modal image registration algorithm under the framework of membrane computing is proposed in this paper, which is named as MCIR algorithm. First, a cell-like P system of membrane structure is designed. Each object in membranes represents a group of transform parameters of floated images. All objects are constantly evolved by the group intelligent algorithm, which obtains the best parameters and transforms them into upper-layer membrane. At the same time, the best objects between the same layers transport randomly in the process of evolution. Finally, the global optimal object is stored in the skin membrane. The proposed MCIR algorithm is evaluated on the multi-modal image, such as the computer tomography (CT) images of the brain, the visible images, and the thermal infrared images. Our algorithm is superior to other methods in terms of properties of global convergence and obtains better registration accuracy and robustness.
