getHist

public int[][] getHist(ISpatialTemporalObj event,

                       boolean left)

Description copied from interface: ISTHistogramProducer

Computes the histogram of the passed in IEvent using the requested dimensions of the underlying data souce.

Specified by:

getHist in interface ISTHistogramProducer

Parameters:

event - The event to extract a histogram of.

dims - The dimensions to use of the underlying data source.

left - Indicates if the event is on the left side of a gap in detections. If true the histogram is extracted from the frame at the end of the event's valid time. Otherwise it is extracted from the frame at the beginning of the passed in event's valid time.

Returns:

The histogram that represents the passed in event.
