Coupled Laplacian Eigenmaps for Locally-Aware 3D Rigid Point Cloud Matching

1 code implementation27 Feb 2024 Matteo Bastico, Etienne Decencière, Laurent Corté, Yannick Tillier, David Ryckelynck

In this work, we propose a new technique, based on graph Laplacian eigenmaps, to match point clouds by taking into account fine local structures.

A Simple and Robust Framework for Cross-Modality Medical Image Segmentation applied to Vision Transformers

2 code implementations9 Oct 2023 Matteo Bastico, David Ryckelynck, Laurent Corté, Yannick Tillier, Etienne Decencière

In this work, we propose a simple framework to achieve fair image segmentation of multiple modalities using a single conditional model that adapts its normalization layers based on the input type, trained with non-registered interleaved mixed data.

Heuristic Hyperparameter Choice for Image Anomaly Detection

no code implementations20 Jul 2023 Zeyu Jiang, João P. C. Bertoldo, Etienne Decencière

Anomaly detection (AD) in images is a fundamental computer vision problem by deep learning neural network to identify images deviating significantly from normality.

Adapting the Hypersphere Loss Function from Anomaly Detection to Anomaly Segmentation

no code implementations23 Jan 2023 Joao P. C. Bertoldo, Santiago Velasco-Forero, Jesus Angulo, Etienne Decencière

We propose an incremental improvement to Fully Convolutional Data Description (FCDD), an adaptation of the one-class classification approach from anomaly detection to image anomaly segmentation (a. k. a.

Giga-SSL: Self-Supervised Learning for Gigapixel Images

1 code implementation6 Dec 2022 Tristan Lazard, Marvin Lerousseau, Etienne Decencière, Thomas Walter

Whole slide images (WSI) are microscopy images of stained tissue slides routinely prepared for diagnosis and treatment selection in medical practice.

[Reproducibility Report] Explainable Deep One-Class Classification

no code implementations6 Jun 2022 Joao P. C. Bertoldo, Etienne Decencière

Fully Convolutional Data Description (FCDD), an explainable version of the Hypersphere Classifier (HSC), directly addresses image anomaly detection (AD) and pixel-wise AD without any post-hoc explainer methods.

A modular U-Net for automated segmentation of X-ray tomography images in composite materials

1 code implementation15 Jul 2021 João P C Bertoldo, Etienne Decencière, David Ryckelynck, Henry Proudhon

X-ray Computed Tomography (XCT) techniques have evolved to a point that high-resolution data can be acquired so fast that classic segmentation methods are prohibitively cumbersome, demanding automated data pipelines capable of dealing with non-trivial 3D images.

Dealing with Topological Information within a Fully Convolutional Neural Network

no code implementations27 Jun 2019 Etienne Decencière, Santiago Velasco-Forero, Fu Min, Juanjuan Chen, Hélène Burdin, Gervais Gauthier, Bruno Laÿ, Thomas Bornschloegl, Thérèse Baldeweck

A fully convolutional neural network has a receptive field of limited size and therefore cannot exploit global information, such as topological information.
