Nonlinear image representation using divisive normalization (2008, methodology): “However, the independent adjustment of the transform coefficients often introduces artifacts such as ripples and halos around high-contrast features, and these need to be eliminated in a post-processing step [6, 14, 3].”
High Dynamic Range Imaging (2015, methodology): “Such an approach has been proposed in the compander algorithm [79], which can serve as a tone mapping operator that reduces the information loss in the subsequent LDR-toHDR conversion.”
Image smoothing via L0 gradient minimization (2011, methodology): “Tone Mapping HDR tone mapping is another popular application that can be achieved by decomposing an HDR image into a piece-wise smooth base layer conveying most of the energy and a detail layer [Tumblin and Turk 1999; Durand and Dorsey 2002; Choudhury and Tumblin 2003; Li et al. 2005; Farbman et al.”
Two-scale tone management for photographic look (2006, methodology): “2005] and activity map [Li et al. 2005] where the local average of the amplitude of high frequencies is used.”
Image deblurring with blurred/noisy image pairs (2007, methodology): “Aggregated image gradients at multiple scales have also been used in HDR compression [Fattal et al. 2002; Li et al. 2005].”
Interactive local adjustment of tonal values (2006, unknown): “…utilize a curve to map each pixel to a display value, [Ward Larson et al. 1997; Reinhard et al. 2002; Drago et al. 2003], and local (spatially variant)operators,[Pattanaiketal.1998;TumblinandTurk 1999; Ashikhmin2002; DurandandDorsey2002;Fattaletal.2002;Reinhard et al. 2002; Li et al. 2005].”
