Class Size

java.lang.Object

fact.features.Size

All Implemented Interfaces:

stream.Processor

public class Size
extends Object
implements stream.Processor

Calculate the feature called Size. A physicist would call this the number of Photons in a shower. This basically sums up all weights that belong to a shower. In short size is the sum of the photonCharge of all showerPixel.
