Samples up to 12 frames of the target window and of the reference (video or image) at 160 px width in RGB, builds 256-bin histograms per channel and derives a monotone 1D LUT: method histogram = histogram specification (CDF matching, midpoint quantiles), method mean_std = per-channel mean and standard deviation transfer (Reinhard et al. 2001, applied in RGB). strength blends the LUT with identity.
