Reconstruction of a cloudy exo-Earth when observed face-on, with θ_orb = 0° and ζ = 90°. Top row: original surface albedo map, together with the two reconstructions using different denoisers, as well as the relative weight for each element on the surface. The next pairs of rows display the original cloud coverage (rows 2 and 4), togetherwith the inferred cloud albedo (rows 3 and 5).
