Property Details

Lc public_oe property

Quantized levels per 'color' component. Power of two, typically 32, 64 or 128.
public int Lc
return int

Lcc public_oe property

Quantized levels per 'color co-occurrence' component. Power of two, typically 16, 32 or 64.
public int Lcc
return int

N1c public_oe property

Number of color vectors used to model normal background color variation at a given pixel. Try 15 for default.
public int N1c
return int

N1cc public_oe property

Number of color co-occurrence vectors used to model normal background color variation at a given pixel. Try 25 for default.
public int N1cc
return int

N2c public_oe property

Number of color vectors retained at given pixel. Must be > N1c, typically ~ 5/3 of N1c.
Used to allow the first N1c vectors to adapt over time to changing background.
public int N2c
return int

N2cc public_oe property

Number of color co-occurrence vectors retained at given pixel. Must be > N1cc, typically ~ 5/3 of N1cc.
Used to allow the first N1cc vectors to adapt over time to changing background.
public int N2cc
return int

T public_oe property

A percentage value which determines when new features can be recognized as new background. (Typically 0.9).
public float T
return float

alpha1 public_oe property

How quickly we forget old background pixel values seen. Typically set to 0.1
public float alpha1
return float

alpha2 public_oe property

Controls speed of feature learning. Depends on T. Typical value circa 0.005.
public float alpha2
return float

alpha3 public_oe property

Alternate to alpha2, used (e.g.) for quicker initial convergence. Typical value 0.1.
public float alpha3
return float

delta public_oe property

Affects color and color co-occurrence quantization, typically set to 2.
public float delta
return float

is_obj_without_holes public_oe property

If 1 we ignore holes within foreground blobs. Defaults to 1.
public int is_obj_without_holes
return int

minArea public_oe property

Discard foreground blobs whose bounding box is smaller than this threshold. Try 15 for default
public float minArea
return float

perform_morphing public_oe property

Number of erode-dilate-erode foreground-blob cleanup iterations.
These erase one-pixel junk blobs and merge almost-touching blobs. Default value is 1.
public int perform_morphing
return int
