Efficient Pairwise Neuroimage Analysis using the Soft Jaccard Index and 3D Keypoint Sets

1 code implementation11 Mar 2021 Laurent Chauvin, Kuldeep Kumar, Christian Desrosiers, William Wells III, Matthew Toews

Our measure generalizes the Jaccard index to account for soft set equivalence (SSE) between keypoint elements, via an adaptive kernel framework modeling uncertainty in keypoint appearance and geometry.

DNA Nucleobase Interaction Driven Electronic and Optical Fingerprints in Gallium Selenide Monolayer for DNA Sequencing Devices

no code implementations9 Feb 2021 Kuldeep Kumar, Munish Sharma

The interaction of DNA nucleobases with monolayer GaSe has been studied with in DFT framework using vdW functional.

White matter fiber analysis using kernel dictionary learning and sparsity priors

no code implementations15 Apr 2018 Kuldeep Kumar, Kaleem Siddiqi, Christian Desrosiers

Results highlight the ability of our method to group streamlines into plausible bundles and illustrate the impact of sparsity priors on the performance of the proposed methods.

White Matter Fiber Segmentation Using Functional Varifolds

no code implementations18 Sep 2017 Kuldeep Kumar, Pietro Gori, Benjamin Charlier, Stanley Durrleman, Olivier Colliot, Christian Desrosiers

We use it to cluster fibers with a dictionary learning and sparse coding-based framework, and present a preliminary analysis using HCP data.

Multi-modal analysis of genetically-related subjects using SIFT descriptors in brain MRI

no code implementations18 Sep 2017 Kuldeep Kumar, Laurent Chauvin, Mathew Toews, Olivier Colliot, Christian Desrosiers

So far, fingerprinting studies have focused on identifying features from single-modality MRI data, which capture individual characteristics in terms of brain structure, function, or white matter microstructure.
