Class BackgroundSubtractorCNT

Namespace

OpenCvSharp

Assembly

OpenCvSharp.dll

Background subtraction based on counting. About as fast as MOG2 on a high end system. More than twice faster than MOG2 on cheap hardware (benchmarked on Raspberry Pi3).

Methods

Create(int, bool, int, bool)

Creates a CNT Background Subtractor

public static BackgroundSubtractorCNT Create(int minPixelStability = 15, bool useHistory = true, int maxPixelStability = 900, bool isParallel = true)

Parameters

minPixelStability int

number of frames with same pixel color to consider stable

useHistory bool

determines if we're giving a pixel credit for being stable for a long time

maxPixelStability int

maximum allowed credit for a pixel in history

isParallel bool

determines if we're parallelizing the algorithm

Returns
