Sauron U-Net: Simple automated redundancy elimination in medical image segmentation via filter pruning

1 code implementation27 Sep 2022 Juan Miguel Valverde, Artem Shatillo, Jussi Tohka

We present Sauron, a filter pruning method that eliminates redundant feature maps by discarding the corresponding filters with automatically-adjusted layer-specific thresholds.

Automatic cerebral hemisphere segmentation in rat MRI with lesions via attention-based convolutional neural networks

1 code implementation4 Aug 2021 Juan Miguel Valverde, Artem Shatillo, Riccardo de Feo, Jussi Tohka

We present MedicDeepLabv3+, a convolutional neural network that is the first completely automatic method to segment cerebral hemispheres in magnetic resonance (MR) volumes of rats with lesions.

Region-wise Loss for Biomedical Image Segmentation

1 code implementation3 Aug 2021 Juan Miguel Valverde, Jussi Tohka

We show that, under the proposed RW loss framework, certain loss functions, such as Active Contour and Boundary loss, can be reformulated similarly with appropriate RW maps, thus revealing their underlying similarities and a new perspective to understand these loss functions.

RatLesNetv2: A Fully Convolutional Network for Rodent Brain Lesion Segmentation

1 code implementation24 Jan 2020 Juan Miguel Valverde, Artem Shatillo, Riccardo de Feo, Olli Gröhn, Alejandra Sierra, Jussi Tohka

RatLesNetv2 obtained similar to higher Dice coefficient values than the other ConvNets and it produced much more realistic and compact segmentations with notably fewer holes and lower Hausdorff distance.

Predicting intelligence based on cortical WM/GM contrast, cortical thickness and volumetry

no code implementations9 Sep 2019 Juan Miguel Valverde, Vandad Imani, John D. Lewis, Jussi Tohka

These last two measurements were derived from the T1-weighted MR images using cortical surfaces produced by the CIVET pipeline.

Automatic Rodent Brain MRI Lesion Segmentation with Fully Convolutional Networks

no code implementations23 Aug 2019 Juan Miguel Valverde, Artem Shatillo, Riccardo de Feo, Olli Gröhn, Alejandra Sierra, Jussi Tohka

Several automatic methods have been developed for different human brain MRI segmentation, but little research has targeted automatic rodent lesion segmentation.
