Abstract
Systems and methods are disclosed that use a Foundational Stereo Model to generate an output disparity map. The Foundational Stereo Model includes side-tuning adapters (STA) that utilize a vision transformer (ViT) and a convolutional neural network (CNN) to generate feature maps. Specifically, the CNN may be used to adapt the ViT-based monocular depth estimation network for the stereo setup, which synergizes the strengths of both CNN and ViT architectures. In addition, the Foundational Stereo Model includes an attentive hybrid cost filtering (AHCF) that uses two branches that also utilizes the advantages of both a transformer architecture and the CNN architecture. Furthermore, the Foundational Stereo Model may perform iterative refinement of an initial disparity map to obtain the output disparity map based on performing a convolutional gated recurrent unit (GRU) operation.
