[edit] Description
TEdgeMask creates an edgemask based off gradient vector magnitude. It includes some useful options such as luma to chroma linking of the edge map and seperate thresholds for each plane. It can output a binary mask or a magnitude mask scaled to a 0-255 range.
[edit] Requirements
[edit] Syntax and Parameters
- TEdgeMask (clip, int "Y", int "U", int "V", float "threshY", float "threshU", float "threshV", int "link", int "type", int "valOn", int "valOff", bool "preBlur")
- clip c =
- Input clip; only YUY2 and YV12 are supported.
- clip c =
- int Y = 1
- int U = 1
- int V = 1
- These control how each of the planes (Y, U, V) is processed.
- Set to 1 to process the plane, set to 0 to not process (as in don't even memset, it will just be garbage), set to -x to have the plane be memset to abs(x) (must be in the range -1 to -255 and -256 = 0).
- int Y = 1
- float threshY = 8.0
- float threshU = 8.0
- float threshV = 8.0
- These set the magnitude thresholds for each plane... if over this value then a pixel will be considered an edge.
- float threshY = 8.0
- int link = 1
- Specifies whether luma to chroma linking, no linking, or linking of every plane to every other plane is used.
- int link = 1
- 0 : no linking
- 1 : luma to chroma linking
- 2 : every plane to every other plane
- int type = 2
- Sets the type of first order partial derivative approximation that is used.
- Possible values:
- int type = 2
- 1 : 2 pixel
- 2 : 4 pixel
- int valOn = 255
- int valOff = 0
- Sets the values to use for the binary mask output. valOn = value for edge pixels, valOff = value for non-edge pixels.
- Set valOn to a negative value and instead of creating a binary mask, TEdgeMask will output a mask with the actual edge magnitude values scaled onto a 0-255 range (with the max value 255 corresponding to a single edge gradient of 255).
- int valOn = 255
- bool preblur = false
- Indicates whether to apply a 3x3 guassian blur to the input image prior to generating the edge map.
- bool preblur = false
[edit] Examples
TEdgeMask with default settings (binary mask output):
AviSource("blah.avi") TEdgeMask (Y=1, U=1, V=1, threshY=8.0, threshU=8.0, threshV=8.0, link=1, type=2, valOn=255, valOff=0, preblur=false)
Magnitude mask output:
AviSource("blah.avi") TEdgeMask (valOn=-1)
