Windows batch files for Nicolas resmpling filters

[markanini]

I'm putting together a series of Windows batch files for state-of the art resampling in IM based on Nicolas guide: http://www.imagemagick.org/Usage/filter/nicolas/

Please let me know if it's a reasonable selection for typical resampling tasks or if the parameters need to be updated.

Sigmoidized LanczosSharp EWA upscale.bat

Code: Select all

magick %1 -colorspace RGB +sigmoidal-contrast 7.5 -filter Lanczos -define filter:blur=.9891028367558475 -distort Resize 200%% -sigmoidal-contrast 7.5 -colorspace sRGB "%~dpn1-SigmoidizedLanczosSharpEWA.png"

Sigmoidized Ginseng Tensor upscale(sharper).bat

Code: Select all

magick %1 -colorspace RGB +sigmoidal-contrast 7.5 -define filter:window=Jinc -define filter:lobes=3 -resize 200%% -sigmoidal-contrast 7.5 -colorspace sRGB "%~dpn1-SigmoidizedGinseng3LobeTensor.png"

Sigmoidized QuadraticJinc EWA upscale(reduce 2nd halo).bat

Code: Select all
