Fig. 7: Reference image with correlation points 
TEST RESULTS 
Results of the correlation test can be found in table 1. The table is split up 
3b I 3 : > . o 
in 'black and white' correlation results, i.e. the black and white correlation 
points are treated independently. A correlation accuracy of 0.5 for example 
means that 50 % of the correlation points have been detected correctly.
