Estimating Extreme 3D Image Rotation with Transformer Cross-Attention

no code implementations5 Mar 2023 Shay Dekel, Yosi Keller, Martin Cadik

In this work, we propose a cross-attention-based approach that utilizes CNN feature maps and a Transformer-Encoder, to compute the cross-attention between the activation maps of the image pairs, which is shown to be an improved equivalent of the 4D correlation volume, used in previous works.
