Method Detail

get

public ARGBType 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.

See http://en.wikipedia.org/wiki/Gray_code

Specified by:

get in interface Sampler<ARGBType>

Overrides:

get in class NLinearInterpolator<ARGBType>

copy

public NLinearInterpolatorARGB copy()

Specified by:

copy in interface RealRandomAccess<ARGBType>

Specified by:

copy in interface Sampler<ARGBType>

Overrides:

copy in class NLinearInterpolator<ARGBType>

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.

printWeights

private final void printWeights()

printCode

private final void printCode()
