Introduction
What is goal of this paper? A robust year-round localization performance even when learned in just a
single day.
Contributions They introduce the classification-based place retrieval pipeline using an
image-shaped point cloud descriptor called SCI (Scan Context Image).
To alleviate false alarms during long-term localization, they propose an entropy-based detection module for unseen places.

What is goal of this paper? Extend the VolxeNet to Multimodal-VoxelNet
Contributions MVX-net effectively fuses multimodal information leading to reduced false
positives and negatives compared to the LiDAR-only VoxleNet
• Pointfusion method
• Voxelfusion method
