Method Detail

copy

public void copy(MultiscaleWarpRB warp)

Copy the given warp

Parameters:

warp - the warp to copy

interpolate

public boolean interpolate(Template tmp1,
                           Template tmp2,
                           boolean sample,

Interpolate this warping function from tmp1 to tmp2

Overrides:

interpolate in class Warp

Parameters:

tmp1 - Source template

tmp2 - target template

sample - should the contour samples be used, or just the control points

borders - Should we pin the border down

Returns:

true if interpolation successful
