Description
Estimating large extreme inter-image rotations is critical for numerous computer vision domains involving images related by limited or non-overlapping fields of view. In this work we propose an attention-based approach with a pipeline of novel algorithmic components. First as rotation estimation pertains to image pairs we introduce an inter-image distillation scheme using Decoders to improve embeddings. Second whereas contemporary methods compute a 4D correlation volume (4DCV) encoding inter-image relationships we propose an Encoder-based cross-attention approach between activation maps to compute an enhanced equivalent of the 4DCV. Finally we present a cascaded Decoder-based technique for alternately refining the cross-attention and the rotation query. Our approach outperforms current state-of-the-art methods on extreme rotation estimation. We make our code publicly available.
