Method Detail

run

public void run(@ByVal
                Mat image,
                @ByRef
                ERStatVector regions)

\brief 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

Parameters:

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.
