Method Detail

get

public T get()

Get the interpolated value at the current position.

To visit the pixels that contribute to an interpolated value, we move in a (binary-reflected) Gray code pattern, such that only one dimension of the target position is modified per move.

Specified by:

get in interface Sampler<R extends RealType<R>>

Overrides:

get in class NLinearInterpolator<T extends AbstractVolatileRealType<R,T>>

See Also:

Gray code.

copy

public ClampingNLinearInterpolatorVolatileRealType<R,T> copy()

Specified by:

copy in interface RealRandomAccess<R extends RealType<R>>

Specified by:

copy in interface Sampler<R extends RealType<R>>

Overrides:

copy in class NLinearInterpolator<T extends AbstractVolatileRealType<R,T>>

Returns:

- A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)

graycodeFwdRecursive

private final void graycodeFwdRecursive(int dimension)

graycodeBckRecursive

private final void graycodeBckRecursive(int dimension)

accumulate

private final void accumulate()

multiply current target value with current weight and add to accumulator.
