The GitHub repository titled "Statewide Visual Geolocalization in the Wild" is associated with a research project presented at the European Conference on Computer Vision (ECCV) in 2024. The project is led by a team of researchers including Florian Fervers, Sebastian Bullinger, Christoph Bodensteiner, Michael Arens, and Rainer Stiefelhagen. The repository serves as a resource for implementing the methods discussed in their paper, which focuses on visual geolocalization techniques applicable in real-world scenarios. The repository includes essential components such as installation instructions, dataset information, training procedures, and evaluation methods. Users are guided to install Jax with GPU support and clone the repository to set up the environment. The dataset utilized for training and evaluation consists of street-view images sourced from the Mapillary platform, along with aerial imagery from various locations in the United States and Germany. For training, users are instructed to configure dataset paths in a YAML file and execute a training script that leverages available GPUs. The results of the training process are stored in a designated output directory. The evaluation process involves creating a reference database for a specified search region, which includes generating embeddings for different cells and creating a FAISS index for efficient retrieval. The repository also provides a script for localizing query images against the reference database, allowing users to assess the performance of the model through recall metrics at various distances. The results indicate the effectiveness of the model in accurately localizing images based on the pretrained weights. Additionally, the repository encourages users to cite the work if they utilize the code or data, providing a citation format for reference. Users are also invited to report any issues they encounter while using the repository, fostering a collaborative environment for further development and improvement of the geolocalization methods presented.

Researchers have developed a new two-stage training method to improve Visual Geo-localization (VG), enhancing its performance in applications like autonomous driving, augmented reality, and SLAM.

The paper titled "Revisit Anything: Visual Place Recognition via Image Segment Retrieval" addresses a significant challenge in the field of visual place recognition, which is essential for the navigation and localization of embodied agents. The authors, Kartik Garg and his colleagues, highlight the limitations of existing methods that typically encode entire images for recognition tasks. These methods struggle when images of the same location are captured from different viewpoints, as the dissimilarities in non-overlapping areas can overshadow the similarities in overlapping regions. To overcome this issue, the authors propose a novel approach that focuses on encoding and retrieving image segments rather than whole images. By utilizing open-set image segmentation, they decompose images into meaningful entities, which they refer to as "things" and "stuff." This segmentation allows for the creation of a new representation called SuperSegment, which consists of multiple overlapping subgraphs that connect segments with their neighboring segments. The authors introduce a method called SegVLAD, which efficiently encodes these SuperSegments into compact vector representations. Their experiments demonstrate that this segment-based retrieval approach significantly improves recognition recall compared to traditional whole-image retrieval methods. The results indicate that SegVLAD sets a new state-of-the-art in place recognition across various benchmark datasets, proving its versatility for both generic and task-specific image encoders. Additionally, the paper explores the broader implications of their method by evaluating its performance in an object instance retrieval task. This evaluation bridges the gap between visual place recognition and object-goal navigation, showcasing the potential of their approach to recognize specific goal objects within a given place. The research was presented at the European Conference on Computer Vision (ECCV) 2024 and includes supplementary materials, with a total of 29 pages and 8 figures. The work contributes to several fields, including computer vision, artificial intelligence, information retrieval, machine learning, and robotics, and is available for further exploration through the provided links.
