Performance Analysis of Registration Measures for Multi-modal Image Registration

摘要: 該文考察了多模態(tài)圖像配準中幾個典型的配準測度，揭示了它們之間的關(guān)系，通過實驗對它們進行了全面的分析比較．實驗中考察的測度主要包括：基于熵的測度、PIU測度以及PIU測度的改進形式等．實驗結(jié)果顯示了這幾個典型配準測度在有效性和適應(yīng)性方面的差異，為實際應(yīng)用中合理選擇這些測度提供可靠的參考．

Abstract: This paper reviews several typical techniques of multi-modal image registra-tion, exposures the relationship among them, and offers a full analysis and comparison using numerical examples. The techniques analyzed in this paper include the ones using those reg-istration measures such as entropy based, PIU (Partition Intensity Uniformity) classes, and correlation coefficient based. The modified PIU criteria are also included. The experimental results demonstrate the effectiveness and accommodation of the techniques, and provide a valid reference in the choice of registration techniques. -
