sync

Synchronize scores of trackScoreLogic objects

Description

example

sync(scoreLogic1,scoreLogic2) sets the values of 'Score' and 'MaxScore' of scoreLogic1 to the values of scoreLogic2.

Examples

collapse all

Create a score logic using the default confirmation and deletion thresholds.

scoreLogic1 = trackScoreLogic
scoreLogic1 = 
  trackScoreLogic with properties:

    ConfirmationThreshold: 20
        DeletionThreshold: -5
                    Score: 0
                 MaxScore: 0

Create a second score logic, specifying the confirmation threshold as 30 and the deletion threshold as -10.

scoreLogic2 = trackScoreLogic('ConfirmationThreshold',30,'DeletionThreshold',-10)
scoreLogic2 = 
  trackScoreLogic with properties:

    ConfirmationThreshold: 30
        DeletionThreshold: -10
                    Score: 0
                 MaxScore: 0

Initialize the two score logics using different target rates in a unit volume.

volume = 1.3; % Volume of a sensor detection bin

beta1 = 0.1;   % New target rate in a unit volume
init(scoreLogic1,volume,beta1);
disp(['Score and MaxScore of ScoreLogic1: ', num2str(output(scoreLogic1))])
Score and MaxScore of ScoreLogic1: 11.6699      11.6699
beta2 = 0.3;   % New target rate in a unit volume
init(scoreLogic2,volume,beta2);
disp(['Score and MaxScore of ScoreLogic2: ', num2str(output(scoreLogic2))])
Score and MaxScore of ScoreLogic2: 12.7685      12.7685

Specify the likelihood that a detection is assigned to the track. Then, update the second score logic with a hit.

likelihood = 0.05 + 0.05*rand(1);
hit(scoreLogic2,volume,likelihood)

disp(['Score and MaxScore of ScoreLogic2: ', num2str(output(scoreLogic2))])
Score and MaxScore of ScoreLogic2: 24.3413      24.3413

Synchronize scoreLogic1 to have the same 'Score' and 'MaxScore' as scoreLogic2. The sync function does not modify the confirmation or deletion thresholds. To verify this, display the properties of both score logic objects.

sync(scoreLogic1,scoreLogic2)
scoreLogic1
scoreLogic1 = 
  trackScoreLogic with properties:

    ConfirmationThreshold: 20
        DeletionThreshold: -5
                    Score: 24.3413
                 MaxScore: 24.3413

scoreLogic2
scoreLogic2 = 
  trackScoreLogic with properties:

    ConfirmationThreshold: 30
        DeletionThreshold: -10
                    Score: 24.3413
                 MaxScore: 24.3413
