A Positive/Unlabeled Approach for the Segmentation of Medical Sequences using Point-Wise Supervision

1 code implementation18 Jul 2021 Laurent Lejeune, Raphael Sznitman

While most methods of this kind assume that the proportion of positive samples in the data is known a-priori, we introduce a novel self-supervised method to estimate this prior efficiently by combining a Bayesian estimation framework and new stopping criteria.

Iterative multi-path tracking for video and volume segmentation with sparse point supervision

no code implementations27 Aug 2018 Laurent Lejeune, Jan Grossrieder, Raphael Sznitman

Our object model is then used in a graph-based optimization problem that takes into account all provided locations and the image data in order to infer the complete pixel-wise segmentation.

Expected exponential loss for gaze-based video and volume ground truth annotation

no code implementations16 Jul 2017 Laurent Lejeune, Mario Christoudias, Raphael Sznitman

Many recent machine learning approaches used in medical imaging are highly reliant on large amounts of image and ground truth data.
