[edit] Description

TEMmod creates an edge mask using gradient vector magnitude. It's based on TEdgeMask written by Kevin Stone (a.k.a. tritical) but rewritten from scratch exclusively for AviSynth 2.6.

[edit] Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24, YV411

• SSE2 capable CPU
• Microsoft Visual C++ 2015 Redistributable Package (x86 / x64)

*** vcredist_x86.exe is required for TEMmod-x86

*** vcredist_x64.exe is required for TEMmod-x64

[edit] Syntax and Parameters

TEMmod (clip, float "threshY", float "threshC", int "type", int "link", int "chroma", bool "invert", bool "preblur", float "scale")

clip   =

Input clip; only planar formats are supported.

float  threshY = 8.0

Set the magnitude thresholds for Y-plane.

If over this value then a sample will be considered an edge, and the output mask will be binarized to by 0 and 255.

Setting this to 0 means output a magnitude mask instead of binary mask.

float  threshC = 8.0

Same as threshY but sets the magnitude thresholds for U-plane and V-plane.

int  type = 4

Sets the type of first order partial derivative approximation that is used.

Possible values:

• 1 : 2 pixel (floating point arithmetic, almost same as original)
• 2 : 4 pixel (floating point arithmetic, almost same as original)
• 3 : 2 pixel (type1 with SSE2 integer arithmetic, a bit incorrect but faster)
• 4 : 4 pixel (type2 with SSE2 integer arithmetic, a bit incorrect but faster)
• 5 : 6 pixel (Sobel operator with SSE2 integer arithmetic)

int  link = 1

Specifies whether luma to chroma linking, no linking, or linking of every plane to every other plane is used.

• 0 : no linking
• 1 : luma to chroma linking
• 2 : every plane to every other plane

int  chroma = 1

This control how chroma (U-plane and V-plane) is processed:

• 0 : do not process
• 1 : process
• 2 : fill with zeroes

bool  invert = false

If this is set to True, the output mask will be inverted.

bool  preblur = false

Indicates whether to apply a 3x3 guassian blur to the input image prior to generating the edge map.

float  scale = 0.0

If output is a magnitude mask(threshY=0), it is scaled by this value.

Setting this to 0 means output is adjusted automatically and scaled onto 0-255 range.

[edit] Examples

TEMmod with default settings:

AviSource("blah.avi")
TEMmod (threshY=8.0, threshC=8.0, type=4, link=1, chroma=1, invert=false, preblur=false, scale=0.0)
