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
