Stereo image super-resolution is a technique that utilizes the additional information provided by binocular systems to enhance the performance of image super-resolution. Previous methods have not fully utilized the cross-view and intra-view information. To address this issue, researchers proposed a Parallax Fusion Transformer (PFT) module consisting of two components: Cross-view Fusion Transformer (CVFT) and Intra-view Refinement Transformer (IVRT). CVFT merges different parallaxes and extracts features from both left and right images while IVRT refines the intra-view features by removing noise and enhancing texture details. The team then combined PFT with Swin Transformer as the backbone for feature extraction and SR reconstruction to form a pure Transformer architecture called PFT-SSR. Extensive experiments and ablation studies were conducted to evaluate the effectiveness of PFT-SSR compared to other state-of-the art methods such as EDSR, RCAN, StereoSR, PASSRnet, iPASSR, and SSRDE–FNett. The results showed that PFT–SSR outperformed most SOTA methods on various datasets, especially on Flickr102. Additionally, an ablation study was conducted on the choice of cross–view interaction technology to demonstrate the strong stereo image fusion ability of PFT which improved model performance more effectively than Swin Transformer Blocks or biPAM. In conclusion, PFT–SSR is a promising approach for stereo image super–resolution that fully utilizes cross–view and intra–view information through its innovative Parallax Fusion Transformer module. Experiments demonstrated its superiority over other state–of–the–art methods in terms of accuracy in reconstructing edges and texture details. The source code for PFT–SSR is available on GitHub.

Abstract: Stereo image super-resolution aims to boost the performance of image super-resolution by exploiting the supplementary information provided by binocular systems. Although previous methods have achieved promising results, they did not fully utilize the information of cross-view and intra-view. To further unleash the potential of binocular images, in this letter, we propose a novel Transformerbased parallax fusion module called Parallax Fusion Transformer (PFT). PFT employs a Cross-view Fusion Transformer (CVFT) to utilize cross-view information and an Intra-view Refinement Transformer (IVRT) for intra-view feature refinement. Meanwhile, we adopted the Swin Transformer as the backbone for feature extraction and SR reconstruction to form a pure Transformer architecture called PFT-SSR. Extensive experiments and ablation studies show that PFT-SSR achieves competitive results and outperforms most SOTA methods. Source code is available at https://github.com/MIVRC/PFT-PyTorch.
