Properties
- BackgroundPrior
Prior probability that each individual pixel is a background pixel.
- DecisionThreshold
Value of decision threshold. Decision value is the value above which a pixel is determined to be foreground.
- DefaultLearningRate
The learning rate of the algorithm. It lies between 0.0 and 1.0. It determines how quickly features are "forgotten" from histograms.
- MaxFeatures
Total number of distinct colors to maintain in histogram.
- MaxVal
Maximum value taken on by pixels in image sequence, e.g. 1.0 or 255.
- MinVal
Minimum value taken on by pixels in image sequence. Usually 0.
- NumFrames
Number of frames used to initialize the background model.
- QuantizationLevels
The parameter used for quantization of color-space. It is the number of discrete levels in each channel to be used in histograms.
- SmoothingRadius
Kernel radius used for morphological operations.
- UpdateBackgroundModel
Status of background model update.
