Faster or Stronger: Towards Flexible Visual Place Recognition via Weighted Aggregation and Token Pruning
The paper presents advancements in Visual Place Recognition (VPR) through a new method called Weighted Aggregated Descriptor (WeiAD). This method improves the aggregation of patch tokens by assigning weights to clusters, enhancing the accuracy of global representations. Additionally, the authors introduce WeiToP, a token pruning framework that optimizes feature extraction costs while maintaining performance.
- ▪Visual Place Recognition aims to match query images to reference images in large-scale databases.
- ▪The proposed WeiAD method enhances VPR performance by weighting clusters during aggregation.
- ▪WeiToP allows for flexible token pruning at inference time, improving efficiency without additional training.
