Conditional Alignment and Uniformity for Contrastive Learning with Continuous Proxy Labels

no code implementations10 Nov 2021 Benoit Dufumier, Pietro Gori, Julie Victor, Antoine Grigis, Edouard Duchesnay

However, a particularity of medical images is the availability of meta-data (such as age or sex) that can be exploited for learning representations.

Contrastive Learning

Template-Based Graph Clustering

1 code implementation5 Jul 2021 Mateus Riva, Florian Yger, Pietro Gori, Roberto M. Cesar Jr., Isabelle Bloch

We propose a novel graph clustering method guided by additional information on the underlying structure of the clusters (or communities).

Graph Clustering

Fast and Scalable Optimal Transport for Brain Tractograms

no code implementations5 Jul 2021 Jean Feydy, Pierre Roussillon, Alain Trouvé, Pietro Gori

The parameters -- blur and reach -- of our method are meaningful, defining the minimum and maximum distance at which two fibers are compared with each other.

Knowledge distillation from multi-modal to mono-modal segmentation networks

no code implementations17 Jun 2021 Minhao Hu, Matthis Maillard, Ya zhang, Tommaso Ciceri, Giammarco La Barbera, Isabelle Bloch, Pietro Gori

In this paper, we propose KD-Net, a framework to transfer knowledge from a trained multi-modal network (teacher) to a mono-modal one (student).

Metamorphic image registration using a semi-Lagrangian scheme

1 code implementation16 Jun 2021 Anton François, Pietro Gori, Joan Glaunès

In this paper, we propose an implementation of both Large Deformation Diffeomorphic Metric Mapping (LDDMM) and Metamorphosis image registration using a semi-Lagrangian scheme for geodesic shooting.

Deep Graphics Encoder for Real-Time Video Makeup Synthesis from Example

no code implementations12 May 2021 Robin Kips, Ruowei Jiang, Sileye Ba, Edmund Phung, Parham Aarabi, Pietro Gori, Matthieu Perrot, Isabelle Bloch

While makeup virtual-try-on is now widespread, parametrizing a computer graphics rendering engine for synthesizing images of a given cosmetics product remains a challenging task.

Virtual Try-on

Approximation of dilation-based spatial relations to add structural constraints in neural networks

no code implementations22 Feb 2021 Mateus Riva, Pietro Gori, Florian Yger, Roberto Cesar, Isabelle Bloch

Several relations can be modeled as a morphological dilation of a reference object with a structuring element representing the semantics of the relation, from which the degree of satisfaction of the relation between another object and the reference object can be derived.

CA-GAN: Weakly Supervised Color Aware GAN for Controllable Makeup Transfer

no code implementations24 Aug 2020 Robin Kips, Pietro Gori, Matthieu Perrot, Isabelle Bloch

While existing makeup style transfer models perform an image synthesis whose results cannot be explicitly controlled, the ability to modify makeup color continuously is a desirable property for virtual try-on applications.

White Matter Fiber Segmentation Using Functional Varifolds

no code implementations18 Sep 2017 Kuldeep Kumar, Pietro Gori, Benjamin Charlier, Stanley Durrleman, Olivier Colliot, Christian Desrosiers

We use it to cluster fibers with a dictionary learning and sparse coding-based framework, and present a preliminary analysis using HCP data.

Comparison of Distances for Supervised Segmentation of White Matter Tractography

1 code implementation4 Aug 2017 Emanuele Olivetti, Giulia Bertò, Pietro Gori, Nusrat Sharmin, Paolo Avesani

For these reasons, in this work we compare many streamline distance functions available in the literature.
