For the rigid registration of multi-modality medical images, mutual information (MI) technique is unsuitable to clinical diagnose because of high computational cost and low robustness. In this paper, a new concept of equivalent meridian plane (EMP) is proposed, and the EMP and other two normal feature planes are determined using principal component analysis (PCA); the rough registrations of those...
In this paper, a novel image attribute, fuzzy edge field (FEF) is defined and used to strengthen the similarity between images. As the feature of images, FEF could be extracted automatically without any manual interaction. A new registration algorithm based on fuzzy edge similarity (FES) was presented. Generalized fuzzy operator (GFO) is utilized to detect edge. Gaussian function is explored to expand...
