Non-phase-shift Fourier single-pixel imaging with conjugate symmetry of the Fourier spectrum and ADMM-based image inpainting

To decrease the number of phase-shift patterns of Fourier single-pixel imaging (FSPI), we present a non-phase-shift FSPI method. In this method, we use only the 0 phase-shift patterns to reconstruct the top and bottom halves of the image separately and then stitch them together to form a complete image. In addition, an image inpainting method based on the alternating direction method of multipliers is adopted to erase the stitching mark. The imaging quality of the proposed non-phase-shift FSPI is similar to multiple-step FSPI. Simulation and experimental results validate the effectiveness of the proposed method.
