Neural Annotation Refinement: Development of a New 3D Dataset for Adrenal Gland Analysis

1 code implementation30 Jun 2022 Jiancheng Yang, Rui Shi, Udaranga Wickramasinghe, Qikui Zhu, Bingbing Ni, Pascal Fua

Besides, we develop a new Adrenal gLand ANalysis (ALAN) dataset with the proposed NeAR, where each case consists of a 3D shape of adrenal gland and its diagnosis label (normal vs. abnormal) assigned by experts.

Deep Active Latent Surfaces for Medical Geometries

no code implementations21 Jun 2022 Patrick M. Jensen, Udaranga Wickramasinghe, Anders B. Dahl, Pascal Fua, Vedrana A. Dahl

During training the latent vectors are constrained to have the same value, which avoids overfitting.

ImplicitAtlas: Learning Deformable Shape Templates in Medical Imaging

no code implementations CVPR 2022 Jiancheng Yang, Udaranga Wickramasinghe, Bingbing Ni, Pascal Fua

Deep implicit shape models have become popular in the computer vision community at large but less so for biomedical applications.

Deep Active Surface Models

no code implementations CVPR 2021 Udaranga Wickramasinghe, Graham Knott, Pascal Fua

Active Surface Models have a long history of being useful to model complex 3D surfaces but only Active Contours have been used in conjunction with deep networks, and then only to produce the data term as well as meta-parameter maps controlling them.

Voxel2Mesh: 3D Mesh Model Generation from Volumetric Data

1 code implementation8 Dec 2019 Udaranga Wickramasinghe, Edoardo Remelli, Graham Knott, Pascal Fua

CNN-based volumetric methods that label individual voxels now dominate the field of biomedical segmentation.

Probabilistic Atlases to Enforce Topological Constraints

1 code implementation18 Sep 2019 Udaranga Wickramasinghe, Graham Knott, Pascal Fua

Probabilistic atlases (PAs) have long been used in standard segmentation approaches and, more recently, in conjunction with Convolutional Neural Networks (CNNs).
