Reconstructions for different overlapping ratio. (a) Reconstructed images under different overlapping ratio with Gaussian noise using different algorithms (Gauss-Newton, TPWFP, FPSR, and TVFP). (b) PSNR for reconstructed images from measurements without noise. (c) PSNR for reconstructed images from measurements with 20 dB SNR Gaussian noise.
