fn as_raw_mut_ERFilter(&mut self) -> *mut c_void

Provided Methods§

fn run( &mut self, image: &impl ToInputArray, regions: &mut Vector<ERStat>, ) -> Result<()>

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
