Recognition of Unseen Bird Species by Learning from Field Guides

1 code implementation3 Jun 2022 Andrés C. Rodríguez, Stefano D'Aronco, Rodrigo Caye Daudt, Jan D. Wegner, Konrad Schindler

Illustrations contained in field guides deliberately focus on discriminative properties of each species, and can serve as side information to transfer knowledge from seen to unseen bird species.

FiLM-Ensemble: Probabilistic Deep Learning via Feature-wise Linear Modulation

1 code implementation31 May 2022 Mehmet Ozgur Turkoglu, Alexander Becker, Hüseyin Anil Gündüz, Mina Rezaei, Bernd Bischl, Rodrigo Caye Daudt, Stefano D'Aronco, Jan Dirk Wegner, Konrad Schindler

We show that the idea can be extended to uncertainty quantification: by modulating the network activations of a single deep network with FiLM, one obtains a model ensemble with high diversity, and consequently well-calibrated estimates of epistemic uncertainty, with low computational overhead in comparison.

Learning Graph Regularisation for Guided Super-Resolution

1 code implementation CVPR 2022 Riccardo de Lutio, Alexander Becker, Stefano D'Aronco, Stefania Russo, Jan D. Wegner, Konrad Schindler

With the decision to employ the source as a constraint rather than only as an input to the prediction, our method differs from state-of-the-art deep architectures for guided super-resolution, which produce targets that, when downsampled, will only approximately reproduce the source.

Digital Taxonomist: Identifying Plant Species in Community Scientists' Photographs

no code implementations7 Jun 2021 Riccardo de Lutio, Yihang She, Stefano D'Aronco, Stefania Russo, Philipp Brun, Jan D. Wegner, Konrad Schindler

Automatic identification of plant specimens from amateur photographs could improve species range maps, thus supporting ecosystems research as well as conservation efforts.

Mapping oil palm density at country scale: An active learning approach

no code implementations24 May 2021 Andrés C. Rodríguez, Stefano D'Aronco, Konrad Schindler, Jan D. Wegner

To that end, we propose a new, active deep learning method to estimate oil palm density at large scale from Sentinel-2 satellite images, and apply it to generate complete maps for Malaysia and Indonesia.

PC2WF: 3D Wireframe Reconstruction from Raw Point Clouds

1 code implementation ICLR 2021 Yujia Liu, Stefano D'Aronco, Konrad Schindler, Jan Dirk Wegner

Next, the corners are linked with an exhaustive set of candidate edges, which is again pruned to obtain the final wireframe.

Crop mapping from image time series: deep learning with multi-scale label hierarchies

1 code implementation17 Feb 2021 Mehmet Ozgur Turkoglu, Stefano D'Aronco, Gregor Perich, Frank Liebisch, Constantin Streit, Konrad Schindler, Jan Dirk Wegner

The three-level label hierarchy is encoded in a convolutional, recurrent neural network (convRNN), such that for each pixel the model predicts three labels at different level of granularity.

Crop Classification under Varying Cloud Cover with Neural Ordinary Differential Equations

1 code implementation4 Dec 2020 Nando Metzger, Mehmet Ozgur Turkoglu, Stefano D'Aronco, Jan Dirk Wegner, Konrad Schindler

We propose to use neural ordinary differential equations (NODEs) in combination with RNNs to classify crop types in irregularly spaced image sequences.

Deep Active Learning in Remote Sensing for data efficient Change Detection

1 code implementation25 Aug 2020 Vít Růžička, Stefano D'Aronco, Jan Dirk Wegner, Konrad Schindler

We investigate active learning in the context of deep neural network models for change detection and map updating.

GeoGraph: Learning graph-based multi-view object detection with geometric cues end-to-end

no code implementations23 Mar 2020 Ahmed Samy Nassar, Stefano D'Aronco, Sébastien Lefèvre, Jan D. Wegner

In this paper we propose an end-to-end learnable approach that detects static urban objects from multiple views, re-identifies instances, and finally assigns a geographic position per object.

Fine-grained Species Recognition with Privileged Pooling: Better Sample Efficiency Through Supervised Attention

1 code implementation20 Mar 2020 Andres C. Rodriguez, Stefano D'Aronco, Konrad Schindler, Jan Dirk Wegner

We propose a scheme for supervised image classification that uses privileged information, in the form of keypoint annotations for the training data, to learn strong models from small and/or biased training sets.

Gating Revisited: Deep Multi-layer RNNs That Can Be Trained

3 code implementations25 Nov 2019 Mehmet Ozgur Turkoglu, Stefano D'Aronco, Jan Dirk Wegner, Konrad Schindler

We propose a new STAckable Recurrent cell (STAR) for recurrent neural networks (RNNs), which has fewer parameters than widely used LSTM and GRU while being more robust against vanishing or exploding gradients.

Guided Super-Resolution as Pixel-to-Pixel Transformation

2 code implementations ICCV 2019 Riccardo de Lutio, Stefano D'Aronco, Jan Dirk Wegner, Konrad Schindler

Guided super-resolution is a unifying framework for several computer vision tasks where the inputs are a low-resolution source image of some target quantity (e. g., perspective depth acquired with a time-of-flight camera) and a high-resolution guide image from a different domain (e. g., a grey-scale image from a conventional camera); and the target output is a high-resolution version of the source (in our example, a high-res depth map).
