Class LinearInterpolationProcessor

java.lang.Object

org.openimaj.ml.timeseries.processor.interpolation.TimeSeriesInterpolation

org.openimaj.ml.timeseries.processor.interpolation.LinearInterpolationProcessor

All Implemented Interfaces:

TimeSeriesProcessor<double[],Double,DoubleTimeSeries>

public class LinearInterpolationProcessor
extends TimeSeriesInterpolation

Perform a linear interpolation such that the value of data at time t1 between t0 and t2 = data[t1] = data[t0] * (t1 - t0)/(t2-t0) + data[t2] * (t2 - t1)/(t2-t0) Note that this means if data is known at t1, then t0 = t1 and data[t1] == data[t0]

Method Detail

interpolate

public DoubleTimeSeries interpolate(DoubleTimeSeries timeSeries,
                                    long[] times)

Specified by:

interpolate in class TimeSeriesInterpolation

times - might be null, therefore some "defualt" time step should be used

Returns:

DoubleTimeSeries instance interpolated from the construction TimeSeries instance
