Parallax‐based second‐order mixed attention for stereo image super‐resolution
IET Computer Vision, 2022 Stereo image pairs can effectively enhance the performance of super‐resolution (SR) since both intra‐view and cross‐view information can be used. However, exploiting cross‐view information accurately is extremely challenging.
