(a) Target spoke pattern. (b) Pre-compressed target pattern, shown together with reference points used for the affine transformation. (c)-(f) Reconstructions without any correction, with only amplitude correction, with only phase correction, with amplitude and phase corrections, respectively, with the camera placed at the focal plane. (g)-(j) Reconstructions for the same parameters as (c)-(f), but at the displaced camera. In (g)-(j), the zeroth order is visible in the top right corners of the images. The values of MSE, SSIM, C, and CNR are shown at the bottom of each corresponding image.
