Release notes

  • demo_TVFP_resChart.m - demonstrate the TVFP algorithm to reconstruct amplitude-only objects (resolution chart)
  • demo_TVFP_complex.m - demonstrate the TVFP algorithm to reconstruct complex objects
  • demo_eTVFP.m - demonstrate the eTVFP algorithm which could estimate pupil function
  • demo_realData.m - demonstrate the reconstruction for real data

Performance evaluation

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.
