Field Details

alpha

public float alpha

Weights importance of image brightness error and velocity smoothness. Larger values which prefer a smooth flow.

SOR_RELAXATION

public float SOR_RELAXATION

SOR relaxation parameter.

numWarps

public int numWarps

Number of warps which it will apply.

maxInnerIterations

public int maxInnerIterations

Maximum number of iterations in the inner loop.

convergeTolerance

public float convergeTolerance

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

pyrScale

public double pyrScale

Change in scale between each layer. Try 0.7

pyrSigma

public double pyrSigma

Amount of 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 InterpolationType interpolation

Type of interpolation used. Bilinear recommended
