Package edu.gsu.cs.dmlab.distance.dtw.shapeseries

Class AggregateShapeSeries

java.lang.Object

edu.gsu.cs.dmlab.distance.dtw.shapeseries.ShapeSeries

edu.gsu.cs.dmlab.distance.dtw.shapeseries.AggregateShapeSeries

All Implemented Interfaces:

IAggregateShapeSeries, IShapeSeries

public class AggregateShapeSeries
extends ShapeSeries
implements IAggregateShapeSeries

Shape series class that shrinks the length and resolution of a series by averaging consecutive point ranges into a single representative point. The number of points averaged from a consecutive range is dependent upon the length of the input shape series and the desired size after being resized.

Constructor

Parameters:

factory - Factory object used for construction of various objects used and returned by this object

ts - The input shape series to be represented by this reduced resolution series

shrunkSize - The size of this series after reduction of the input series

Method Detail

aggregatePtSize

public int aggregatePtSize(int idx)

Description copied from interface: IAggregateShapeSeries

Method that returns the number of points that were used to produce the aggregate point at the indicated index of the time series.

Specified by:

aggregatePtSize in interface IAggregateShapeSeries

Parameters:

idx - The index of the point to get the information for

Returns:

The number of points in the original time series that were used to produce the aggregate point
