Advanced Uses for Bilateral
A few clever, exemplary applications…
Flash/No Flash Image Merge(Petschnigg2004,Eisenman2004)
Tone Management (Bae 2006)
Exposure Correction (Bennett2006) (See also: Bennett 2007 Multispectral Bilateral Video Fusion, IEEE Trans. On Img Proc)
‘Joint’ or ‘Cross’ Bilateral Filter (CBF)
Enhanced ability to find weak details in noise (B’s weights preserve similar edges in A)
Useful Residues for ‘Detail Transfer’
CBF(A,B) to remove A’s noisy details
CBF(B,A) to remove B’s less-noisy details;
add to CBF(A,B) for clean, detailed, sharp image
(See the papers for details)
Tonal Management(Bae et al., SIGGRAPH 2006)
Cross bilateral, residues visually compelling image decompositions.
Explore: adjust component contrast, find visually pleasing transfer functions, etc.
Stylize: finds transfer functions that match histograms of preferred artists,
‘Textureness’; local measure of textural richness; can use this to guide local mods to match artist’s
Conclusions
Bilateral Filter easily adapted, customized to broad class of problems
One tool among many for complex problems
Useful in for any task that needsRobust, reliable smoothing with outlier rejection
