From: Restoration of X-ray phase-contrast imaging based on generative adversarial networks

Comparison of phase-contrast images generated by different methods: (a) Stripe image: shows the stripe image containing object information. (b) Label image: serves as the target output of the GAN, guiding the model’s training. (c) Phase-contrast image generated by the Fourier algorithm: phase-contrast image generated after processing with the Fourier algorithm. (d) Phase-contrast image generated by the GAN: phase-contrast image generated after processing with the GAN.
