Fig. 10: Guided photon processing.
From: CASPI: collaborative photon processing for active single-photon imaging
a We propose guided photon processing to recover the photon fluxes in low SNR scenarios. Guided photon processing uses spatial frequency correlations between the intensity image and the photon transient cube. b Guided photon processing and thresholding are adaptively selected based on the estimated cubelet SNR to generate the optimal initial flux estimates leading to optimal scene property estimates.
