CARE 2D denoising and upsampling example data

Example data for 2D CARE denoising/upsampling consisting of pairs of low and high signal-to-noise ratio (SNR) 2D images of cells. The high SNR images are acquistions of Human U2OS cells taken from the Broad Bioimage Benchmark Collection and the low SNR images were created by synthetically adding strong read-out and shot-noise and applying pixel binning of 2x2, thus mimicking acquisitions at a very low light level.
