The MCvFGDStatModelParams type exposes the following members.

Fields

  NameDescription
Public fieldalpha1
How quickly we forget old background pixel values seen. Typically set to 0.1
Public fieldalpha2
Controls speed of feature learning. Depends on T. Typical value circa 0.005.
Public fieldalpha3
Alternate to alpha2, used (e.g.) for quicker initial convergence. Typical value 0.1.
Public fielddelta
Affects color and color co-occurrence quantization, typically set to 2.
Public fieldis_obj_without_holes
If 1 we ignore holes within foreground blobs. Defaults to 1.
Public fieldLc
Quantized levels per 'color' component. Power of two, typically 32, 64 or 128.
Public fieldLcc
Quantized levels per 'color co-occurrence' component. Power of two, typically 16, 32 or 64.
Public fieldminArea
Discard foreground blobs whose bounding box is smaller than this threshold. Try 15 for default
Public fieldN1c
Number of color vectors used to model normal background color variation at a given pixel. Try 15 for default.
Public fieldN1cc
Number of color co-occurrence vectors used to model normal background color variation at a given pixel. Try 25 for default.
Public fieldN2c
Number of color vectors retained at given pixel. Must be > N1c, typically ~ 5/3 of N1c.
Public fieldN2cc
Number of color co-occurrence vectors retained at given pixel. Must be > N1cc, typically ~ 5/3 of N1cc.
Public fieldperform_morphing
Number of erode-dilate-erode foreground-blob cleanup iterations.
Public fieldT
A percentage value which determines when new features can be recognized as new background. (Typically 0.9).
