Abstract
In order to improve visual place recognition, a computer implemented method for determining an image descriptor (V(X)) is provided. The method comprises the steps of: a) clustering features from a feature map () into a plurality of feature clusters by determining for each feature an inter-cluster weight (α); b) for each feature cluster obtained in step a), determining and assigning an intra-cluster saliency weight (β) to each feature that is associated with said feature cluster; and c) determining the image descriptor (V(X)) based on the inter-cluster weight (α) and the intra-cluster saliency weight (β).
