Country-Scale Cropland Mapping in Data-Scarce Settings Using Deep Learning: A Case Study of Nigeria

1 code implementation18 Dec 2023 Joaquin Gajardo, Michele Volpi, Daniel Onwude, Thijs Defraeye

In this study, we explore the usefulness of combining a global cropland dataset and a hand-labeled dataset to train machine learning models for generating a new cropland map for Nigeria in 2020 at 10 m resolution.

What You See is What You Classify: Black Box Attributions

1 code implementation23 May 2022 Steven Stalder, Nathanaël Perraudin, Radhakrishna Achanta, Fernando Perez-Cruz, Michele Volpi

These attributions are provided in the form of masks that only show the classifier-relevant parts of an image, masking out the rest.

Semisupervised Manifold Alignment of Multimodal Remote Sensing Images

no code implementations15 Apr 2021 Devis Tuia, Michele Volpi, Maxime Trolliet, Gustau Camps-Valls

We introduce a method for manifold alignment of different modalities (or domains) of remote sensing images.

A survey of active learning algorithms for supervised remote sensing image classification

no code implementations15 Apr 2021 Devis Tuia, Michele Volpi, Loris Copa, Mikhail Kanevski, Jordi Munoz-Mari

Defining an efficient training set is one of the most delicate phases for the success of remote sensing image classification routines.

Decision fusion with multiple spatial supports by conditional random fields

no code implementations24 Aug 2018 Devis Tuia, Michele Volpi, Gabriele Moser

In this paper, we follow these two observations and encode them as priors in an energy minimization framework based on conditional random fields (CRFs), where classification results obtained at pixel and region levels are probabilistically fused.

Deep multi-task learning for a geographically-regularized semantic segmentation of aerial images

no code implementations23 Aug 2018 Michele Volpi, Devis Tuia

When approaching the semantic segmentation of overhead imagery in the decimeter spatial resolution range, successful strategies usually combine powerful methods to learn the visual appearance of the semantic classes (e. g. convolutional neural networks) with strategies for spatial regularization (e. g. graphical models such as conditional random fields).
