The key method of ERFilter algorithm.
Takes image on input and returns the selected regions in a vector of ERStat only distinctive ERs which correspond to characters are selected by a sequential classifier
image | Single channel image CV_8UC1 |
regions | Output for the 1st stage and Input/Output for the 2nd. The selected Extremal Regions are stored here. |
Extracts the component tree (if needed) and filter the extremal regions (ER's) by using a given classifier.
