WebbResearchGate WebbTo minimize the Laplacian energies of the residuals, the guided image and the input image are first passed through a sparse Laplacian filter. The sparse Laplacian filter with MLRI is shown in Table 1. Then MLRI uses the guided filter to generate the tentative estimation of the R (R ⌣) image. The interpolated G image is used as the guided ...

WebbFor linear enhancement, the selection of filters g ^ m (ω) (and thus k ^ m (ω)) makes little difference.However, this is not true for the nonlinear case. For the nonlinear approach described later, we show that a Laplacian filter should be favored. By selecting a Laplacian filter, we can be assured that positions of extrema will be unchanged and …
