Since january 2021, I am mainly involved in the BIOMEDE project. This project aims at better characterizing, by using machine learning or deep learning methods, the tumors of patients with diffuse intrinsic pontine gliomas (DIPG) which is a rare pediatric cancer with a very poor prognosis. The analysis is based on clinical and imaging (multi-parametric MRI) features. Action: Conference submitted

Preprint ArXiv

Our preprint is now available on ArXiv A Mutual Reference Shape for Segmentation Fusion and Evaluation Abstract : This paper proposes the estimation of a mutual shape from a set of different segmentation results using both active contours and information theory. The mutual shape is here defined as a consensus shape estimated from a set of different segmentations of the same object. In an original manner, such a shape is defined as the minimum of a criterion that benefits from both the mutual information and the joint entropy of the input segmentations. This energy criterion is justified using similarities between information theory quantities and area measures, and presented in a continuous variational framework. In order to solve this shape optimization problem, shape derivatives are computed for each term of the criterion and interpreted as an evolution equation of an active contour. A mutual shape is then es
