Comparison between GIPCC and other conventional GI techniques which reconstruct the full 160 × 160 pixel image. All figures are automatically gray-scale compensated. (a) The direct image of the object. (b)–(d) Images retrieved by GIPCC, ΔGI, and g 2 with 11940 patterns and a PSNR of 8.312, 8.311, and 8.188 dB, respectively, (e) and (f) are R + positive and R − negative correspondence images, from 5882 and 6058 patterns, with PSNRs of 7.425 and 5.562 dB, respectively, (g) is the image Δ G obtained by averaging all 11940 patterns but with G − inverted, with a PSNR of 8.088 dB.
