training with the operator
regions, representing characters, including their gray values (region
and pixel) and the corresponding class name will be written into a
file. An arbitrary number of regions within one image is
supported. For each character (region) in
corresponding class name must be specified in
Class. If no
file extension is specified in
TrainingFile the extension '.trf'
is appended to the file name. In contrast to
write_ocr_trainf one image per character is passed. The
domain of this image defines the pixels which belong to the
character. The file format can be defined by the parameter
'ocr_trainf_version' of the operator
