Member Function Documentation

__fromPtr__()

static new BackgroundSubtractorLSBP OpenCVForUnity.BgsegmModule.BackgroundSubtractorLSBP.__fromPtr__ ( IntPtr addr )

static

apply() [1/2]

override void OpenCVForUnity.BgsegmModule.BackgroundSubtractorLSBP.apply ( Mat image, Mat fgmask )

virtual

Computes a foreground mask.

Parameters

image	Next video frame.
fgmask	The output foreground mask as an 8-bit binary image.
learningRate	The value between 0 and 1 that indicates how fast the background model is learnt. Negative parameter value makes the algorithm to use some automatically chosen learning rate. 0 means that the background model is not updated at all, 1 means that the background model is completely reinitialized from the last frame.

Reimplemented from OpenCVForUnity.VideoModule.BackgroundSubtractor.

apply() [2/2]

override void OpenCVForUnity.BgsegmModule.BackgroundSubtractorLSBP.apply ( Mat image, Mat fgmask, double learningRate )

virtual

Computes a foreground mask.

Parameters

image	Next video frame.
fgmask	The output foreground mask as an 8-bit binary image.
learningRate	The value between 0 and 1 that indicates how fast the background model is learnt. Negative parameter value makes the algorithm to use some automatically chosen learning rate. 0 means that the background model is not updated at all, 1 means that the background model is completely reinitialized from the last frame.

Reimplemented from OpenCVForUnity.VideoModule.BackgroundSubtractor.

Dispose()

override void OpenCVForUnity.BgsegmModule.BackgroundSubtractorLSBP.Dispose ( bool disposing )

protectedvirtual

Reimplemented from OpenCVForUnity.VideoModule.BackgroundSubtractor.

getBackgroundImage()

override void OpenCVForUnity.BgsegmModule.BackgroundSubtractorLSBP.getBackgroundImage ( Mat backgroundImage )

virtual

Computes a background image.

Parameters

backgroundImage

The output background image.

Note

Sometimes the background image can be very blurry, as it contain the average background statistics.

Reimplemented from OpenCVForUnity.VideoModule.BackgroundSubtractor.
