NeuroNCAP: Photorealistic Closed-loop Safety Testing for Autonomous Driving

3 code implementations11 Apr 2024 William Ljungbergh, Adam Tonderski, Joakim Johnander, Holger Caesar, Kalle Åström, Michael Felsberg, Christoffer Petersson

We present a versatile NeRF-based simulator for testing autonomous driving (AD) software systems, designed with a focus on sensor-realistic closed-loop evaluation and the creation of safety-critical scenarios.

Autonomous Driving

You can have your ensemble and run it too -- Deep Ensembles Spread Over Time

no code implementations20 Sep 2023 Isak Meding, Alexander Bodin, Adam Tonderski, Joakim Johnander, Christoffer Petersson, Lennart Svensson

We find that DESOT obtains the benefits of deep ensembles, in terms of predictive and uncertainty estimation performance, while avoiding the added computational cost.

Autonomous Driving Out-of-Distribution Detection

Raw or Cooked? Object Detection on RAW Images

no code implementations21 Jan 2023 William Ljungbergh, Joakim Johnander, Christoffer Petersson, Michael Felsberg

Images fed to a deep neural network have in general undergone several handcrafted image signal processing (ISP) operations, all of which have been optimized to produce visually pleasing images.

Future Object Detection with Spatiotemporal Transformers

1 code implementation21 Apr 2022 Adam Tonderski, Joakim Johnander, Christoffer Petersson, Kalle Åström

In order to make accurate predictions about the future, it is necessary to capture the dynamics in the scene, both object motion and the movement of the ego-camera.

Dense Gaussian Processes for Few-Shot Segmentation

1 code implementation7 Oct 2021 Joakim Johnander, Johan Edstedt, Michael Felsberg, Fahad Shahbaz Khan, Martin Danelljan

Given the support set, our dense GP learns the mapping from local deep image features to mask values, capable of capturing complex appearance distributions.

Deep Gaussian Processes for Few-Shot Segmentation

no code implementations30 Mar 2021 Joakim Johnander, Johan Edstedt, Martin Danelljan, Michael Felsberg, Fahad Shahbaz Khan

Through the expressivity of the GP, our approach is capable of modeling complex appearance distributions in the deep feature space.

Learning Video Instance Segmentation with Recurrent Graph Neural Networks

no code implementations7 Dec 2020 Joakim Johnander, Emil Brissman, Martin Danelljan, Michael Felsberg

Most existing approaches to video instance segmentation comprise multiple modules that are heuristically combined to produce the final output.
