Field Detail

alpha

public float alpha

Brightness difference weighting factor. Larger values which prefer a smooth flow.

gamma

public float gamma

Gradient difference weighting factor. Larger values which prefer a smooth flow.

SOR_RELAXATION

public float SOR_RELAXATION

SOR relaxation parameter. 0 < w < 2. Recommended default is 1.9

numOuter

public int numOuter

Number of iterations in the outer loop

numInner

public int numInner

Number of iterations in the inner loop

maxIterationsSor

public int maxIterationsSor

Maximum allowed iterations for SOR

convergeToleranceSor

public float convergeToleranceSor

Convergence tolerance for SOR loop. Specified in per pixel error.

pyrScale

public double pyrScale

Change in scale between each layer. Try 0.75

pyrSigma

public double pyrSigma

Amount of gaussian blur applied to each layer in the pyramid. If sigma ≤ 0 then no blur is applied.

pyrMaxLayers

public int pyrMaxLayers

Maximum number of layers in the pyramid

interpolation

public TypeInterpolate interpolation

Type of interpolation used. Bilinear recommended
