Field Detail

learnRate

public float learnRate

Specifies how fast it will adapt to changes in the background. From 0 to 1, inclusive. 0 = static 1.0 = instant.

threshold

public float threshold

Threshold for classifying a pixel as background or not. This threshold is applied to the computed Mahalanobis from the distribution. An appropriate threshold will vary depending on the number of bands in the image.

initialVariance

public float initialVariance

The initial variance assigned to a new pixel. Larger values to reduce false positives due to under sampling. Don't set to zero since that can cause divided by zero errors.

minimumDifference

public float minimumDifference

Minimum Euclidean distance between the mean background and observed pixel value for it to be considered moving. This value is automatically scaled for the number of bands in the image.

interpolation

public TypeInterpolate interpolation

Specifies which interpolation it will use. TypeInterpolate.BILINEAR or TypeInterpolate.NEAREST_NEIGHBOR recommended.

ONLY USED FOR MOVING BACKGROUNDS!
