Cortical analysis of heterogeneous clinical brain MRI scans for large-scale neuroimaging studies

no code implementations2 May 2023 Karthik Gopinath, Douglas N. Greve, Sudeshna Das, Steve Arnold, Colin Magdamo, Juan Eugenio Iglesias

Here we present the first method for cortical reconstruction, registration, parcellation, and thickness estimation for clinical brain MRI scans of any resolution and pulse sequence.

A deep learning framework for segmentation of retinal layers from OCT images

no code implementations22 Jun 2018 Karthik Gopinath, Samrudhdhi B Rangrej, Jayanthi Sivaswamy

Segmentation of retinal layers from Optical Coherence Tomography (OCT) volumes is a fundamental problem for any computer aided diagnostic algorithm development.

HyperDense-Net: A hyper-densely connected CNN for multi-modal image segmentation

3 code implementations9 Apr 2018 Jose Dolz, Karthik Gopinath, Jing Yuan, Herve Lombaert, Christian Desrosiers, Ismail Ben Ayed

Therefore, the proposed network has total freedom to learn more complex combinations between the modalities, within and in-between all the levels of abstraction, which increases significantly the learning representation.

Segmentation of retinal cysts from Optical Coherence Tomography volumes via selective enhancement

no code implementations21 Aug 2017 Karthik Gopinath, Jayanthi Sivaswamy

The robustness of the algorithm was examined by cross-validation on the DME and AEI (private) datasets and a mean DC values obtained were 0. 69 and 0. 79, respectively.

Clustering Segmentation

Domain knowledge assisted cyst segmentation in OCT retinal images

no code implementations8 Dec 2016 Karthik Gopinath, Jayanthi Sivaswamy

OCT is one such modality which has great importance in the context of analysis of cystoid structures in subretinal layers.
