[edit] Description

Deen is a set of assembly-optimised denoisers, like various 3d and 2d convolutions.

Note:

  • Deen beta 2 is the older version, unfortunately is also the most known and used version (most of the scripts that use Deen use syntax that's specific to beta 2).
  • Deen v1.0 beta 1 is the updated version and it includes these changes:
    • Original meth parameter renamed to mode
    • Original mode parameter renamed to rad
    • New modes "c2d", "w2d", "w3d" ("m2d" is no longer supported)
    • ti (temporal influence) is now controlled independently by tthY and tthUV (luma/chroma), input value is now an integer (use to be float).
    • New parameters: min, scd, fcf, borderfix
  • Be aware that using the updated version as a drop-in replacement without adjusting the parameters to match the original can result in different behavior.


[edit] Requirements

  • AviSynth 2.5.8 or later
  • Progressive input only
  • Supported color formats: YV12
  • ISSE compatible CPU.


[edit] Syntax and Parameters

deen (clip, string "meth", int "mode", int "thrY", int "thrUV", float "ti")


clip   =
Input clip.


string  meth = "c3d"
Choose a denoising method:
  • "c3d"  : Mode 0 - 1 (default)
  • "a3d"  : Mode 0 - 4
  • "a2d"  : Mode 0 - 7
  • "m2d" : Mode 0 - 20


int  mode = 0
With "c3d", it's the weight matrix.
  • 0 <121> matrix (default)
  • 1 <111> matrix (softer)
With all other methods, it's the spatial radius.
  • 0 : default
  • 1 : 3x3
  • 2 : 5x5
  • 3 : 7x7
  • 4 : 9x9
  • 5 : 11x11
  • 6 : 13x13
  • 7 : 15x15
  • 8 : 17x17
  • 9 : 19x19
  • 10 : 21x21
  • 11 : 23x23
  • 12 : 25x25
  • 13 : 27x27
  • 14 : 29x29
  • 15 : 31x31
  • 16 : 33x33
  • 17 : 35x35
  • 18 : 37x37
  • 19 : 39x39
  • 20 : 41x41


int  thrY = 10
Luma (Y) threshold; higher values blend more.
Range: 0 - 255


int  thrUV = 12
Chroma (UV) threshold; higher values blend more.
Range: 0 - 255


float  ti = 3.0
Temporal influence.
Maximal mean local temporal difference allowed to enable 3D filtering.
If ti is less than or equal to 0, 3d is disabled, use a 2d mode instead.

Deen is a set of assembly-optimised denoisers, like various 3d and 2d convolutions.

[edit] Syntax and Parameters


Deen (clip, string "mode", int "rad", int "thrY", int "thrUV", int "tthY", int "tthUV", float "min", float "scd", string "fcf", bool "borderfix")


clip   =
Input clip.


string  mode = "c3d"
Choose a denoising method:
  • "a2d"
  • "a3d"
  • "c2d"
  • "c3d" - (default)
  • "w2d"
  • "w3d"
Each of the three modes (a, c, w) will take into account pixels around in order to compute the new value. They will only take pixels that are under the threshold (meaning that they are not too different from the original pixel).
  • Now, with the 'c' mode, you only make an average of the surrounding pixels (under the threshold) in order to calculate the new pixel.
  • With the 'a' mode, you do the same, but the threshold is reduced with the distance. Which means that pixels farther will have to be closer to the pixel considered in order to be taken into account.
  • Finally, the mode 'w' changes the weight of a pixel according to its distance from the original pixel. Meaning, instead of averaging all the surrounding pixels under the threshold, it will use the weight instead.
    Pixels close to the center will have a weight of 3 (for example, I don't know exactly the formula), pixels a bit farther a weight of 2, and the farthest pixels, a weight of 1 (they will count three times less than the closest pixels).


int  rad = 1
Radius.
Range: 1-4 in 3d, 1-7 in 2d
  • 1 : 3x3 - (default)
  • 2 : 5x5
  • 3 : 7x7
  • 4 : 9x9
  • 5 : 11x11
  • 6 : 13x13
  • 7 : 15x15


int  thrY = 7
Luma (Y) threshold; higher values blend more.
Range: 0 - 255


int  thrUV = 9
Chroma (UV) threshold; higher values blend more.
Range: 0 - 255


int  tthY = 4
Temporal Luma (Y) threshold. 3d only.
Range: 0 - 255


int  tthUV = 6
Temporal Chroma (UV) threshold. 3d only.
Range: 0 - 255


float  min = 0.5
When using 'a' mode, it's how the threshold is reduced with the raising of the distance
When using 'c', it should do nothing (theoretically - not tested).
When using 'w' mode, it's how the weight of the pixel is reduced when its distance is raising.
1.0 = no reduction ... 0.0 = maximum reduction (range: 0.0 - 1.0)


float  scd = 9.0
Scene change detection; threshold over which a 2d mode is used, in order not to have a temporal ghosting with high motion.
Higher values means potentially more ghosting.


string  fcf = ""
Full control file; default is "", which means no fcf. It allows an overriding of the parameters for ranges of frames.
Check demo.fcf.txt in the zip file.


bool  borderfix = false
Undocumented parameter.


[edit] Examples

  • Deen beta 2 with default settings:
AviSource("Blah.avi")
deen(meth="c3d", mode=0, thrY=10, thrUV=12, ti=3.0)
  • Deen v1.0 beta 1 with all default settings:
AviSource("Blah.avi")
Deen(mode="c3d", rad=1, thrY=7, thrUV=9, tthY=4, tthUV=6, min=0.5, scd=9.0, fcf="", borderfix=false)


[edit] Changelog

2003-08-13 v1.0 beta 1:
 - this is the latest version and includes additional features
2003-01-19 beta 2: - public release - "w3d" not implemented
