Field Detail

learnRate

protected float learnRate

Specifies how fast it will adapt. 0 to 1, inclusive. 0 = static 1.0 = instant.

threshold

protected float threshold

Threshold for classifying a pixel as background or not. If euclidean distance less than or equal to this value it is background.

Constructor Detail

BackgroundMovingBasic

public BackgroundMovingBasic(float learnRate,
                             float threshold,
                             boofcv.struct.distort.PointTransformModel_F32<Motion> transform,
                             boofcv.struct.image.ImageType<T> imageType)

Configures background model

Parameters:

learnRate - learning rate, 0 to 1. 0 = fastest and 1 = slowest.

threshold - Euclidean distance threshold. Background is ≤ this value

transform - Point transform

imageType - Type of input image
