Registering Image Volumes using 3D SIFT and Discrete SP-Symmetry
Laurent Chauvin, William Wells, Matthew Toews
This paper proposes to extend local image features in 3D to include invariance to discrete symmetry including inversion of spatial axes and image contrast. A binary feature sign $s…
Curating Subject ID Labels using Keypoint Signatures
Laurent Chauvin, Matthew Toews
Subject ID labels are unique, anonymized codes that can be used to group all images of a subject while maintaining anonymity. ID errors may be inadvertently introduced manually err…
Efficient Pairwise Neuroimage Analysis using the Soft Jaccard Index and 3D Keypoint Sets
Laurent Chauvin, Kuldeep Kumar, Christian Desrosiers +2
We propose a novel pairwise distance measure between image keypoint sets, for the purpose of large-scale medical image indexing. Our measure generalizes the Jaccard index to accoun…
Large Scale Indexing of Generic Medical Image Data using Unbiased Shallow Keypoints and Deep CNN Features
L. Chauvin, M. Ben Lazreg, J. B. Carluer +2
We propose a unified appearance model accounting for traditional shallow (i.e. 3D SIFT keypoints) and deep (i.e. CNN output layers) image feature representations, encoding respecti…
WaveletBrain: Characterization of human brain via spectral graph wavelets
Majid Masoumi, Matthew Toews, Herve Lombaert
Early diagnosis of Alzheimer's disease plays a key role in understanding the degree of the patient's mental decline and determining preventive therapies. In this study, we introduc…
Keypoint Transfer for Fast Whole-Body Segmentation
Christian Wachinger, Matthew Toews, Georg Langs +2
We introduce an approach for image segmentation based on sparse correspondences between keypoints in testing and training images. Keypoints represent automatically identified disti…
