MAAD: A Model and Dataset for "Attended Awareness" in Driving

1 code implementation16 Oct 2021 Deepak Gopinath, Guy Rosman, Simon Stent, Katsuya Terahata, Luke Fletcher, Brenna Argall, John Leonard

Our model takes as input scene information in the form of a video and noisy gaze estimates, and outputs visual saliency, a refined gaze estimate, and an estimate of the person's attended awareness.

Probabilistic Data Association via Mixture Models for Robust Semantic SLAM

1 code implementation24 Sep 2019 Kevin Doherty, David Baxter, Edward Schneeweiss, John Leonard

The result is a max-mixture-type model that accounts for multiple data association hypotheses as well as incorrect loop closures.

Self-Supervised Visual Place Recognition Learning in Mobile Robots

no code implementations11 May 2019 Sudeep Pillai, John Leonard

Place recognition is a critical component in robot navigation that enables it to re-establish previously visited locations, and simultaneously use this information to correct the drift incurred in its dead-reckoned estimate.

Direction-Aware Semi-Dense SLAM

no code implementations18 Sep 2017 Julian Straub, Randi Cabezas, John Leonard, John W. Fisher III

To aide simultaneous localization and mapping (SLAM), future perception systems will incorporate forms of scene understanding.

SLAM with Objects using a Nonparametric Pose Graph

2 code implementations19 Apr 2017 Beipeng Mu, Shih-Yuan Liu, Liam Paull, John Leonard, Jonathan How

The \textit{data association} and \textit{simultaneous localization and mapping} (SLAM) problems are, individually, well-studied in the literature.

Multi-Volume High Resolution RGB-D Mapping with Dynamic Volume Placement

no code implementations23 Nov 2015 Michael Salvato, Ross Finman, John Leonard

We present a novel RGB-D mapping system for generating 3D maps over spatially extended regions with higher resolution than current methods using multiple, dynamically placed mapping volumes.

Monocular SLAM Supported Object Recognition

no code implementations4 Jun 2015 Sudeep Pillai, John Leonard

In this work, we develop a monocular SLAM-aware object recognition system that is able to achieve considerably stronger recognition performance, as compared to classical object recognition systems that function on a frame-by-frame basis.
