Description
This is a very strong and fast unsharp mask with some new features.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
Syntax and Parameters
- UnsharpHQ (clip, int "THRESHOLD", float "SHARPSTR", float "SMOOTH", bool "SHOW")
- clip =
- Input clip.
- clip =
- int THRESHOLD = 20
- The value that determines whether or not to sharpen a pixel based on the luminance change between their neighbors.
- Lower values allow more to be sharpened (including noise); higher values allow less but is set to high, small detail will not be sharpened.
- Range: 0 to 99
- int THRESHOLD = 20
- float SHARPSTR = 4.0
- Sharpening strength; values from 2.0 to 10.0 are recommended.
- Range: 0.0 up to 99.0
- float SHARPSTR = 4.0
- float SMOOTH = 0.5
- The smoothing strength for pixels not being sharpened (mainly flat areas). Set to 0.0 to disable smoothing.
- Range: 0.0 to 4.0
- float SMOOTH = 0.5
- bool SHOW = false
- When set to true a green and black mask is shown; useful for finding an optimal value* for THRESHOLD.
- Anything in green gets sharpened, anything in black is not sharpened but can be smoothed if SMOOTH is greater than 0.
- bool SHOW = false
- *optimal value - noise vs detail trade-off. The goal is to try to sharpen as much detail as possible while not sharpening noise.
Examples
UnsharpHQ with default settings:
AviSource("Blah.avi") UnsharpHQ(THRESHOLD=20, SHARPSTR=4.0, SMOOTH=0.5, SHOW=false)
Changelog
Version Date Changes
v0.5 2014/01/19 - Released source code under GPLv3 - Added parameters THRESHOLD, SMOOTH, and SHOW - Renamed parameter STR to SHARPSTR
v0.4 2011/02/26 - Optimized and more accurate v0.3
v0.3 2011/02/21 - Initial public release
