Localiser
Class DetectionGroupLocaliser

java.lang.Object
  Localiser.DetectionGroupLocaliser

public class DetectionGroupLocaliser
extends java.lang.Object

Class to provide localisation functions for PamDetections which contain > 1 sub detections. The first iteration of this is being written for the purposes of working out where bearing lines from multiple manually tracked clicks cross and it's likely it will all need to be re-written one day !

Method Detail

localiseDetectionGroup

public boolean localiseDetectionGroup(GroupDetection groupDetection,
                                      int side)

calculate the position of detecion assuming that sub detections all contain bearings, which are probably ambiguous, so will calculate for one side or another - +1 = right of track, -1 = left of track. No other values are allowed !

Parameters:

groupDetection -

side - -1 or 1 for left and right

Returns:

true of localisation calculated successfully

localiseDetectionGroup

public boolean localiseDetectionGroup(GroupDetection groupDetection,
                                      int side,
                                      double groupSize)

Calcuates the position of a detection assuming that sub detections all contain bearings, which are probably ambiguous. If groupSize > 0, then atempt to group clicks into fewer categories to speed up fit. (Not implemented).

Parameters:

groupDetection -

side - -1 or 1 for left and right

groupSize -

Returns:

true of localisation calculated successfully

boolean useDetection(PamDetection subDetection,
                     int sideIndex)
