TCVN_CMCM_CONTOURS_MATCH_I1 |
Contours are compared using the sum over the differences between the reciprocal individual characteristics. |
|
TCVN_CMCM_CONTOURS_MATCH_I2 |
Contours are compared using the sum over the differences between the individual characteristics. |
|
TCVN_CMCM_CONTOURS_MATCH_I3 |
Contours are compared using only the maximum difference between the individual characteristics. |

Die verfügbaren Methoden basieren auf Hu-Invarianten. Sie verwenden die folgenden Algorithmen, wobei A für die erste und B für die zweite Kontur steht.
und 
mit i in [1, 7] sind jeweils Hu Momente von A und B.
