关于asharp....|『影音数码技术学习交流』 - 『漫游』酷论坛

Usage of asharp :
First, add the following line in your .avs script :

LoadPlugin("asharp.dll") # because Avisynth 2.5 doesn't support Autoloading yet

To do simple unsharp masking with a strength of 2x :

asharp(2,0)

To try some adaptive sharpenning :

asharp(2,4)

Suggestion for divx anime decoding :

asharp(2.5,4.5,0.25,hqbf=true)

Syntax :
asharp(float "T", float "D", float "B", bool "hqbf")

T : unsharp masking threshold. 0 will do nothing. (value clamped to [nothing=0..32])

1 is like 32 with ffdsow/Vdub unsharp mask filter, it'll enhance contrast 1x
default is T=2

D : adaptive sharpenning strength. (value clamped to [disabled=0..16])

set to 0 to disable
if D>0, adaptive thresholding is enabled.
the threshold is adapted for each pixel (bigger for edges)
if adaptive sharpenning is enabled, T acts like a maximum.
default is D=4

B : block adaptive sharpenning. (value clamped to [disabled=0..4])

set to a negative value to disable.
if B>=0, block adaptive sharpenning is enabled.
it acts very simply, by lowering the threshold around DCT-blocks edges.
if you use it, avoid any non mod8 cropping between the decoder and asharp.
(it works only wit adaptive sharpenning, when D>0)
default is B=-1 (disabled)

hqbf : high quality block filtering. (aka block based adaptive thresholding.)
