Required Methods

Provided Methods

The character classifier must return a (ranked list of) class(es) id(’s)

Parameters
  • image: Input image CV_8UC1 or CV_8UC3 with a single letter.
  • recognition_probabilities: For each of the N characters found the classifier returns a list with class probabilities for each class.
  • oversegmentation: The classifier returns a list of N+1 character locations’ x-coordinates, including 0 as start-sequence location.
