Fluorescence lifetime images of SKOV3 cancer cells expressing pcDNA3.1-mClover from a SPAD-CCD based microscope. (a) Intensity image from the CCD sensor at a spatial resolution of \(304 \times 152\) pixels. (b) Lifetime image obtained from the SPAD sensor with a resolution of \(76 \times 38\) pixels. (c) Reconstructed image upscaled by a factor of \(4 \times 4\) to the same resolution as (a). (d) The lifetime distributions of the reconstructed image and the low spatial resolution dataset from the SPAD sensors (Ground Truth). (e) The pixel-by-pixel difference between low-resolution data and the reconstruction downsampled to the same pixel resolution.
