The curse of language biases in remote sensing VQA: the role of spatial attributes, language diversity, and the need for clear evaluation

no code implementations28 Nov 2023 Christel Chappuis, Eliot Walt, Vincent Mendez, Sylvain Lobry, Bertrand Le Saux, Devis Tuia

While new, improved and less-biased datasets appear as a necessity for the development of the promising field of RSVQA, we demonstrate that more informed, relative evaluation metrics remain much needed to transparently communicate results of future RSVQA methods.

Deep learning for classification of noisy QR codes

no code implementations20 Jul 2023 Rebecca Leygonie, Sylvain Lobry, ), Laurent Wendling (LIPADE)

We wish to define the limits of a classical classification model based on deep learning when applied to abstract images, which do not represent visually identifiable objects. QR codes (Quick Response codes) fall into this category of abstract images: one bit corresponding to one encoded character, QR codes were not designed to be decoded manually.

How to find a good image-text embedding for remote sensing visual question answering?

no code implementations24 Sep 2021 Christel Chappuis, Sylvain Lobry, Benjamin Kellenberger, Bertrand Le Saux, Devis Tuia

Visual question answering (VQA) has recently been introduced to remote sensing to make information extraction from overhead imagery more accessible to everyone.

Contextual Semantic Interpretability

1 code implementation18 Sep 2020 Diego Marcos, Ruth Fong, Sylvain Lobry, Remi Flamary, Nicolas Courty, Devis Tuia

Once the attributes are learned, they can be re-combined to reach the final decision and provide both an accurate prediction and an explicit reasoning behind the CNN decision.

RSVQA: Visual Question Answering for Remote Sensing Data

no code implementations16 Mar 2020 Sylvain Lobry, Diego Marcos, Jesse Murray, Devis Tuia

We report the results obtained by applying a model based on Convolutional Neural Networks (CNNs) for the visual part and on a Recurrent Neural Network (RNN) for the natural language part to this task.

Semantically Interpretable Activation Maps: what-where-how explanations within CNNs

no code implementations18 Sep 2019 Diego Marcos, Sylvain Lobry, Devis Tuia

This gives the user insight into what the model has seen, where, and a final output directly linked to this information in a comprehensive and interpretable way.

Half a Percent of Labels is Enough: Efficient Animal Detection in UAV Imagery using Deep CNNs and Active Learning

no code implementations17 Jul 2019 Benjamin Kellenberger, Diego Marcos, Sylvain Lobry, Devis Tuia

We present an Active Learning (AL) strategy for re-using a deep Convolutional Neural Network (CNN)-based object detector on a new dataset.

Wasserstein Adversarial Regularization (WAR) on label noise

1 code implementation8 Apr 2019 Kilian Fatras, Bharath Bhushan Damodaran, Sylvain Lobry, Rémi Flamary, Devis Tuia, Nicolas Courty

Noisy labels often occur in vision datasets, especially when they are obtained from crowdsourcing or Web scraping.

Correcting rural building annotations in OpenStreetMap using convolutional neural networks

no code implementations24 Jan 2019 John E. Vargas-Muñoz, Sylvain Lobry, Alexandre X. Falcão, Devis Tuia

Rural building mapping is paramount to support demographic studies and plan actions in response to crisis that affect those areas.

Scale equivariance in CNNs with vector fields

no code implementations31 Jul 2018 Diego Marcos, Benjamin Kellenberger, Sylvain Lobry, Devis Tuia

We study the effect of injecting local scale equivariance into Convolutional Neural Networks.
