Table 1. Accuracy comparisons between different integral property inference methods: PI-NEB=direct integral property inference in NEB-FLIM, PBA-NEB=mean of pixel-wise lifetime estimated by NEB-FLIM, PA=mean of pixel-wise lifetime estimated by pixel-wise analysis, and GA=mean of pixel-wise lifetime estimated by global analysis. The error criteria is square root of mean square error $e({\tau }_k)$ for $k=1,2$. All results in the table are shown in ps.
