Return the pointer to the algorithm object

Gets the dense optical flow pointer.

Stopping criterion threshold used in the numerical scheme, which is a trade-off between precision and running time

Coefficient for additional illumination variation term

Inner iterations (between outlier filtering) used in the numerical scheme

Weight parameter for the data term, attachment parameter

Median filter kernel size (1 = no filter) (3 or 5)

Outer iterations (number of inner loops) used in the numerical scheme

Pointer to the unmanaged object

Number of scales used to create the pyramid of images

Step between scales (less than 1)

Time step of the numerical scheme

Weight parameter for (u - v)^2, tightness parameter

Use initial flow

Number of warpings per scale
