Abstract:

We propose a new method for remote sensing image matching. The proposed method uses encoder subnetwork of an autoencoder pre-trained on GTCrossView data to construct image features. A discriminator network trained on University of California Merced Land Use/Land Cover dataset (LandUse) and High-resolution Satellite Scene dataset (SatScene) computes a match score between a pair of computed image features. We also propose a new network unit, called residual-dyad, and empirically demonstrate that networks that use residual-dyad units outperform those that do not. We compare our approach with both traditional and more recent learning-based schemes on LandUse and SatScene datasets, and the proposed method achieves the state-of-the-art result in terms of mean average precision and ANMRR metrics. Specifically, our method achieves an overall improvement in the performance of 11.26% and 22.41%, respectively, for LandUse and SatScene benchmark datasets.
