BackgroundSubtractorCNT

Objective-C

@interface BackgroundSubtractorCNT : BackgroundSubtractor

Swift

class BackgroundSubtractorCNT : BackgroundSubtractor

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).
