Intelligent Reference Curation for Visual Place Recognition Via Bayesian Selective Fusion
نویسندگان
چکیده
A key challenge in visual place recognition (VPR) is recognizing places despite drastic appearance changes due to factors such as time of day, season, weather or lighting conditions. Numerous approaches based on deep-learnt image descriptors, sequence matching, domain translation, and probabilistic localization have had success addressing this challenge, but most rely the availability carefully curated representative reference images possible places. In letter, we propose a novel approach, dubbed Bayesian Selective Fusion, for actively selecting fusing informative determine best match given query image. The selective element our approach avoids counterproductive fusion every enables dynamic selection environments with changing conditions (such indoors flickering lights, outdoors during sunshowers over day-night cycle). provides means multiple that accounts their varying uncertainty via training-free likelihood function VPR. On difficult from two benchmark datasets, demonstrate matches exceeds performance several alternative along state-of-the-art techniques are provided prior (unfair) knowledge images. Our well suited long-term robot autonomy where commonplace since it training-free, descriptor-agnostic, complements existing matching.

Visual place recognition using Bayesian filtering with Markov chains
We present a novel idea to use Bayesian filtering in the case of place recognition. More precisely, our system combines global image characterization, Learned Vector Quantization, Markov chains and Bayesian filtering. The goal is to integrate several images seen by a robot during exploration of the environment and the dependency between them. We present our system and the new Bayesian filtering...

متن کاملA Bayesian approach for place recognition
This paper presents a robust place recognition algorithm for mobile robots that can be used for planning and navigation tasks. The proposed framework combines nonlinear dimensionality reduction, nonlinear regression under noise, and Bayesian learning to create consistent probabilistic representations of places from images. These generative models are incrementally learnt from very small trainin...
