Description

Non-linear Unsharp Masking, uses a wide-range Gaussian instead of a small-range kernel. Like most sharpeners, this script only processes luma, chroma channels are simply copied from the input clip.

Requirements

Required Plugins

Additional planar colorspaces are supported when using AviSynth 2.6 and appropriate MaskTools2.

Syntax and Parameters

NonlinUSM (clip o, float "z", float "pow", float "str", float "rad", float "ldmp")


clip  o =
Input clip


float  z = 6.0
zero point


float  pow = 1.6
power


float  str = 1.0
strength


float  rad = 9.0
radius for "gauss"


float  ldmp = 0.001
damping for very small differences


Examples

NonlinUSM with default settings: 

AviSource("Blah.avi")
NonlinUSM(z=6.0, pow=1.6, str=1.0, rad=9.0, ldmp=0.001)

More Examples: 

NonlinUSM(pow=4)                          ## enhance: for low bitrate sources
NonlinUSM(z=3, pow=4.0, str=1, rad=6)     ## enhance less
NonlinUSM(z=3, str=0.5, rad=9, pow=1)     ## enhance less

NonlinUSM(z=6, str=1.5, rad=0.6).Sharpen(0.3)  ## sharpen: for hi-q sources
NonlinUSM(z=3, str=2.5, rad=0.6)          ## sharpen: less noise
NonlinUSM(z=6, pow=1.0, str=1, rad=6)     ## unsharp 
 
NonlinUSM(pow=1.0, rad=2, str=0.7)        ## "smoothen" for noisy sources
NonlinUSM(pow=1.0, rad=18, str=0.5)       ## smear: soft glow

NonlinUSM(z=6, pow=4.0, str=1, rad=36)    ## local contrast 
NonlinUSM(z=6, pow=1.0, str=1, rad=36)    ## local contrast 
NonlinUSM(z=16, pow=4.0, str=18, rad=6)   ## B+W psychedelic 
NonlinUSM(z=16, pow=2.0, str=2, rad=36)   ## solarized
NonlinUSM(z=16, pow=4.0, str=3, rad=6)    ## sepia/artistic


Changelog

Version         Date            Changes
