StegoGAN: Leveraging Steganography for Non-Bijective Image-to-Image Translation

no code implementations29 Mar 2024 Sidi Wu, Yizi Chen, Samuel Mermet, Lorenz Hurni, Konrad Schindler, Nicolas Gonthier, Loic Landrieu

Most image-to-image translation models postulate that a unique correspondence exists between the semantic classes of the source and target domains.

Cross-attention Spatio-temporal Context Transformer for Semantic Segmentation of Historical Maps

1 code implementation19 Oct 2023 Sidi Wu, Yizi Chen, Konrad Schindler, Lorenz Hurni

Even though our application is on segmenting historical maps, we believe that the method can be transferred into other fields with similar problems like temporal sequences of satellite images.

BuyTheDips: PathLoss for improved topology-preserving deep learning-based image segmentation

1 code implementation23 Jul 2022 Minh On Vu Ngoc, Yizi Chen, Nicolas Boutry, Jonathan Fabrizio, Clement Mallet

Our method is an extension of the BALoss [1], in which we want to improve the leakage detection for better recovering the closeness property of the image segmentation.

ICDAR 2021 Competition on Historical Map Segmentation

1 code implementation27 May 2021 Joseph Chazalon, Edwin Carlinet, Yizi Chen, Julien Perret, Bertrand Duménieu, Clément Mallet, Thierry Géraud, Vincent Nguyen, Nam Nguyen, Josef Baloun, Ladislav Lenc, Pavel Král

Task~2 consists in segmenting map content from the larger map sheet, and was won by the UWB team using a U-Net-like FCN combined with a binarization method to increase detection edge accuracy.

Combining Deep Learning and Mathematical Morphology for Historical Map Segmentation

no code implementations6 Jan 2021 Yizi Chen, Edwin Carlinet, Joseph Chazalon, Clément Mallet, Bertrand Duménieu, Julien Perret

Our contribution is a pipeline that combines the strengths of CNN (efficient edge detection and filtering) and MM (guaranteed extraction of closed shapes) in order to achieve such a task.
