Description: The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. The term image registration is most commonly used to denote the process of alignment of images , that is of transforming them to the common coordinate system. This is done by optimizing a similarity measure between the two images. A widely used measure is Mutual Information (MI). This method requires estimating joint histogram of the two images. Experiments are presented that demonstrate the approach. The technique is intensity-based rather than feature-based. As a comparative assessment the performance based on normalized mutual information and cross correlation as metric have also been presented.-The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images.

Description: In this paper, we propose a novel registration
algorithm based on minimal spanning tree. First, we extracted
uniform sub-sampling points from image. Second, based on the
feature points, in addition to using pixel intensity, we also added
region based feature to include more spatial information. The
proposed method is evaluated by performing registration
experiments on BrainWeb database. The experimental results
show that the proposed method achieves better robustness while
maintaining good registration accuracy, compared to the
conventional normalized mutual information (NMI) based
registration method. Platform: |

Description: Investigatingmulti-feature information-theoretic image registration,
we introduce consistent and asymptotically unbiased
kth-nearest neighbor (kNN) estimators of mutual information
(MI), normalized MI and exclusive information applicable to
high-dimensional random variables, and derive under closedform
their gradient flows over finite- and infinite-dimensional
transform spaces. Using these results, we devise a novel unsupervisedmethod
for the groupwise registration of cardiac perfusionMRI
exams. Here, local time-intensity curves are used
as a dense set of spatio-temporal features, and statistically
matched through variational optimization. Experiments on
simulated and real datasets suggest the accuracy of the model
for the affine registration of exams with up to 34 frames. Platform: |

Description: In this paper, we propose a novel medical
registration approach based on minimal spanning tree. The
proposed approach has the following contributions. (1)
Compared with single type of feature points, we extracted
corner-like and edge-like points from image, and added a few
random points to cover the low contrast regions. (2) Instead of
fixing the multi-feature points in the whole procedure, they are
hierarchically updated at different registration stages. (3)
Based on the feature points, in addition to using pixel intensity,
we also added region based feature to include more spatial
information. The proposed method is evaluated by performing
registration experiments on BrainWeb. The experimental
results show that the proposed method achieves better
robustness while maintaining good registration accuracy,
compared to the conventional normalized mutual information
(NMI) based registration method Platform: |
