摘要：A super-resolution method using the bilateral filter has recently been proposed. In this letter, we improve its image reconstruction capability by extending the bilateral filter used in that method to the spatially anisotropic filter and show with experiments that the reconstruction error in the proposed method is lower than the previous method using the isotropic bilateral filter.
