Multiscale and Multitopic Sparse Representation for Multisensor Infrared Image Superresolution

Figure 10

Visual comparison of four test images: (a) LR image, (b) original HR image, (c) results obtained using the nearest neighbor interpolation, (d) results obtained using the cubic B-spline interpolation, (e) results obtained using the sparse representation-based method, and (f) results obtained using the proposed method.
