Class BasicExtraction

java.lang.Object

fact.extraction.BasicExtraction

All Implemented Interfaces:

stream.Processor

public class BasicExtraction
extends Object
implements stream.Processor

This processor performs a basic extraction on the data array. It contains three steps: 1. Calculates the position of the max amplitude in [startSearchWindow,startSearchWindow+rangeSearchWindow[ 2. Calculates the position of the half height in front of the maxAmplitudePosition 3. Calculates the integral by summing up the following integrationWindow slices beginning with the half heigth position The resulting photoncharge is calculated by dividing the integral by the integralGain of the pixel

This processor also serves as a basic class for extraction processors
