Accuracy Validation for Medical Image Registration Algorithms:a Review

Accuracy validation is essential to clinical application of medical image registration techniques. Registration validation remains a challenging problem in practice mainly due to lack of 'ground truth'. In this paper, an overview of current validation methods for medical image registration is presented with detailed discussion of their benefits and drawbacks. Special focus is on non-rigid registration validation. Promising solution is also discussed.

隐性冲突话语的策略探析

通过影视、文学作品中的相关实例,本文分析了隐性冲突话语中挑战方与应战方常使用的策略,并将双方的策略进行了对比。结果发现:双方共同使用的策略有提问、陈述、提及、许诺四种;不同的是,挑战方还使用评价、暗讽等策略,而应战方则使用引用、形式化同意等策略。本研究进一步丰富了对隐性冲突话语的认识,对交际策略研究也有一定意义。
