|
Recognition thresholds (recognition-thresholds) |
|
|
| license-plates-diff |
The number of characters that differ, at which two variants of the LP are still considered to belong to the same vehicle. As the parameter increases, the probability that different LPs will be considered the same increases. |
0...11 |
3 |
|
| license-plates-cmp-scores |
Estimation of the LP similarity threshold for the license-plates-diff parameter. The lower the value, the more likely it is that different LP symbols will be considered the same. |
0.000…1.000 |
0.8 |
|
| brand-model-score |
Lower threshold for assessing the accuracy of vehicle model recognition. If the score is lower, then these recognition results are not considered. |
0.000…1.000 |
0.5 |
|
| license-plate-score |
The lower threshold of the accuracy of recognition of the LP. |
0.000…1.000 |
0.2 |
|
| vehicle-type-score |
The lower threshold for evaluating the accuracy of vehicle type recognition. |
0.000…1.000 |
0.8 |
|
|
