Single-Image Super-Resolution Using Panchromatic Gradient Prior and Variational Model

Figure 3

SR results of images “Flower,” “Leaf,” and “Lena” with magnification factor of 2. Each odd line from left to right: original images; results by bicubic interpolation; results by SC method; results by SCBP method; results by our method. Each even line from left to right: the magnification of the small red rectangle in the corresponding each example.
