New Features:

• Added individual thresholds for symbols and plate features depending on the region to improve recognition accuracy. You can find these thresholds in the .env-vanilla file:

  • API_SYMBOL_THRESHOLD_RUS
  • API_SYMBOL_THRESHOLD_EU_CIS
  • API_SYMBOL_THRESHOLD_UK_ASIA
  • API_SYMBOL_THRESHOLD_CHN
  • API_SYMBOL_THRESHOLD_MNG
  • API_SYMBOL_THRESHOLD_UAE
  • API_SYMBOL_THRESHOLD_PERSIAN
  • API_SYMBOL_THRESHOLD_AMERICA
  • API_FEATURE_THRESHOLD_CHN
  • API_FEATURE_THRESHOLD_UAE
  • API_FEATURE_THRESHOLD_RUS

• Added API_AGGREGATED_LP_SCORE_CALC_POLICY parameter to choose the method of aggregated plate score calculation. Use one of the available methods: Multiplication (multiply symbols scores), Average (sum symbols scores divided by the number of symbols), or Median (median value). Select the method to improve accuracy and adapt calculations for specific tasks;

• Added API_NON_ZEROING_LP_DATA_SCORE_THRESHOLD parameter to allow zeroing out data when the plate recognition score is low;
• Added the API_COMPLEXED_SCORE_CALC_POLICY parameter that allows to calculate aggregated license plate score based on averaging the plate recognition score and the plate’s country recognition score.

General changes

• Fixed bugs.
