I think x_0 refers to the corrupted image and x is the (denoised/upscaled/inpainted) image the optimization algorithm tries to come up. Without R(x) the optimal solution is simply x=x0. So we need a good R(x) that can measure how good or natural the solution image is. In this work the R(x) is constraining the valid x to those that can be represented by a CNN. |
