Description
Summary:Image Registration(IR) has been widely applied in biomedical image processing. It is the process of finding an optimal geometric transformation to align two images, which could be defined as a parameter optimization issue. Genetic Algorithm(GA) is one of the most efficient methods for solving complex optimization problems and it has been applied to the real-coding IR problem. However, the classical GA suffers from premature convergence and is easy to fall into local optimum. Inspired by heterosis, which is a common phenomenon in biology, this study proposes an improved GA. By artificially simulating the breeding process of Chinese three-line hybrid rice, known as a successful application of heterosis, the original crossover and mutation mechanisms of GA are improved, and a dynamic diversity controller is designed. This study conducts several multimodal biomedical IR experiments to compare the improved GA with state-of-the-art IR methods, the results show that the proposed method outperforms the others in most scenarios with faster convergence speed and greater robustness.
