STA-VPR: Spatio-temporal Alignment for Visual Place Recognition

1 code implementation • 25 Mar 2021 • Feng Lu, Baifan Chen, Xiang-Dong Zhou, Dezhen Song

Here we split the holistic mid-layer features into local features, and propose an adaptive dynamic time warping (DTW) algorithm to align local features from the spatial domain while measuring the distance between two images.
