) -> Result<()>

Find groups of Extremal Regions that are organized as text blocks.

Parameters

  • img: Original RGB or Greyscale image from wich the regions were extracted.

  • channels: Vector of single channel images CV_8UC1 from wich the regions were extracted.

  • regions: Vector of ER's retrieved from the ERFilter algorithm from each channel.

  • groups: The output of the algorithm is stored in this parameter as set of lists of indexes to provided regions.

  • groups_rects: The output of the algorithm are stored in this parameter as list of rectangles.

  • method: Grouping method (see text::erGrouping_Modes). Can be one of ERGROUPING_ORIENTATION_HORIZ, ERGROUPING_ORIENTATION_ANY.

  • filename: The XML or YAML file with the classifier model (e.g. samples/trained_classifier_erGrouping.xml). Only to use when grouping method is ERGROUPING_ORIENTATION_ANY.

  • minProbablity: The minimum probability for accepting a group. Only to use when grouping method is ERGROUPING_ORIENTATION_ANY.

C++ default parameters

  • method: ERGROUPING_ORIENTATION_HORIZ
  • filename: std::string()
  • min_probablity: 0.5
