Field Details

output_sigma_factor

public double output_sigma_factor

Spatial bandwidth. Proportional to target size.

sigma

public double sigma

gaussian kernel bandwidth

lambda

public double lambda

Regularization term.

interp_factor

public double interp_factor

Weighting factor mixing old track image and new one. Effectively adjusts the rate at which it can adjust to changes in appearance. Values closer to zero slow down the rate of change. 0f is no update. 0.075f is recommended.

maxPixelValue

public double maxPixelValue

Maximum pixel value. Used to normalize image. 8-bit images are 255

padding

public double padding

How much padding is added around the region requested by the user. Specified as fraction of original image. Padding of 1 = 2x original size.

workSpace

public int workSpace

Length of size in work space image. A total of N*N points are sampled. Should be set to a power of two to maximize speed. In general, larger numbers are more stable but slower.

checkValidity

public void checkValidity()

Description copied from interface: Configuration

Checks to see if the configuration is valid. If it is invalid, throw an exception explaining what is incorrect.
