4. CONCLUSION 
Automated impact crater detection algorithms were developed 
to identify various sizes of impact craters under different 
conditions such as illumination angles and geographical 
complexity. The algorithm developed here shows a reliable 
detection accuracy for crater rim locations under many different 
conditions when the automated crater locations were compared 
against the MCC catalogue and manual measurements. 
Currently, the MCC catalogue covers craters, which have 
diameters >Skm. The algorithm described here appears to have 
great potential for extending the range of the MCC catalogue to 
a much wider range of crater diameters especially with the 
release of new high resolution Mars optical images such as 
HRSC, where manual measurements are unlikely to be 
practicable.
