2.1. Common parameter

  • Name (string, must be set) Unique attribute name
  • Type (string, must be "ExtractedInfoString") attribute type
  • Weight (double, default: 1) вес признака
  • Probability (double, default: 0.75) degree of confidence threshold
  • Contour (bool, default: true) not used

2.2. Extra parameters

  • field (string, default: "") filed name for checking
  • allowed (list of ints, default: empty) names of allowed fields, must be separated with spaces
  • partially (int, default: 0) if not 0, then partial matching is allowed (so that the element from allowed is a substring of the value being retrieved).

2.3. Example

Using logic attributes (OR and NOT) output of CNN detector can be separated on static and dynamic classes.
