iBoW-LCD: An Appearance-Based Loop-Closure Detection Approach Using Incremental Bags of Binary Words

Open access

Abstract

In this letter, we introduce iBoW-LCD, a novel appearance-based loop-closure detection method. The presented approach makes use of an incremental bag-of-words (BoW) scheme based on binary descriptors to retrieve previously seen similar images, avoiding any vocabulary training stage usually required by classic BoW models. In addition, to detect loop closures, iBoW-LCD builds on the concept of dynamic islands, a simple but effective mechanism to group similar images close in time, which reduces the computational times typically associated with Bayesian frameworks. Our approach is validated using several indoor and outdoor public datasets, taken under different environmental conditions, achieving a high accuracy and outperforming other state-of-the-art solutions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A bag-of-words algorithm can fail in completely unknown environments.

    “utilizing only the global descriptor instead of a BoW algorithm which can fail in completely unknown environments [48].”

    From Keypoint Detection and Description through Deep Learning in Unstructured Environments (2023) · cites this paper as [48]

    The Introduction (p. 1) says that an offline BoW vocabulary trained on images unlike the current environment can lead to additional false detections. But the paper also presents an incremental BoW method designed to avoid that limitation, so it does not support the claim as a general statement about BoW algorithms in completely unknown environments.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
