Diagram showing quantified evaluation of the results obtained by automatic pathway and semi-supervised alternative. Upper: percent match (PM) curves of 29 cases; Lower: correspondence ratio (CR) curves of 29 cases in two groups. We can see in case no. 2, 11, 15, 17 and 18, low PM and CR were observed in automate pathway but not in semi-supervised group; Case 29 show poor PM but good CR in both groups. Beside these cases, some trace difference could be observed in case no. 22, 26 and 28.
