From: Efficient robust image interpolation and surface properties using polynomial texture mapping
Leave-one-out test. (a) PSNRs for PTM + RBF. (b) PSNRs for PTM. (c) PSNRs for PTM + RBF, non-leave-one-out test, for comparison. (d) Correct interpolant for lighting direction (e) PTM + RBF interpolant, PSNR = 30.803 (note camera flare from other images in the set). (f) PTM interpolant: the PSNR = 30.763, which is acceptable, but not using RBF results in poor modelling of specular content and wrong shadows.
