EdgeLevel

Revision as of 22:58, 30 January 2022

Description

EdgeLevel adjusts the contrast near the edges, the edges are emphasized without overshoot. It may be good to use it after enlargement. It is designed to be applied more strongly only to the contour lines of animation, etc.

AviSynth plugin ported from the Aviutl plugin EdgeLevel by flash3kyuu.

NOTE: Documentation was translated from Japanese with online translators, some words may be not be accurate.

Requirements

• AviSynth+ x86/x64
• Supported color formats: Y8, YV12, YV16, YV24
  • All planar YUV formats (8/10/12/14/16-bit) are supported.

Syntax and Parameters

edgelevel (clip, int "strength", int "threshold", int "bc", int "wc", int "thread", int "simd")

clip   =

Input clip.

int  strength = 10

Adjusts the edge emphasis level. A positive value will emphasize the edges, and a negative value will blur the edges.

• Range: -31 - 31

int  threshold = 16

This is a threshold value that ignores noise.

• Range: 0 - 255

int  bc = 0

Black correction; the original brightness is basically maintained during filtering. It is used when you want to darken the outline intentionally with a chute.

The change in brightness is local. Since the weighting has been adjusted, it is more difficult to shoot at simple color boundaries, and is only applied more strongly to contour lines, such as animations.

• Range: 0 - 31

int  wc = 0

White correction; this is the opposite of black correction.

• Range: 0 - 31

int  threads = 0

The number of parallel threads.

• 0 : auto
• Range: 0 - 32

int  simd = 0

CPU optimization:

• 0 : auto
• 1 : SSE2
• 2 : AVX2

Accelerated with AVX2 / SSE2. The fastest one is automatically selected according to the environment.

Examples

edgelevel with default settings:

AviSource("Blah.avi")
edgelevel (strength=10, threshold=16, bc=0, wc=0, thread=0, simd=0)
