The source image used for the screenshots below is a small cropped region of
[Latin-Portuguese]
Manuel Bernardes Branco Dictionary, Lisbon, 1879 (p. 143, 300 dpi grayscale)
from Clara OCR.
The training image window shows a magnified clipping of the
source image
after binarization according to the
select page format of the training dialog.
The yellow highlighted sector marks the RB (Raw Box)
in focus containing several colored patterns. Green pixels are
selectable for training and red pixels are trainable as the next
pattern. Blue pixels show trained patterns, hence not selectable again
for training in the current session.
Tracing for a certain trained pattern can help selecting several
patterns for training automatically. The training image window shows the
selection according to the
trace page format
of the training dialog.
The screenshot shows a typical view of the select page format of the
training dialog, according to the
training image window after training.
The screenshot shows a typical view of the trace page format of the
training dialog, according to the
training image window after tracing.
The screenshot shows the maintenance window containing the database
which is displayed by a tree browser. Every database item has an own
tree node describing properties by short comments. For all
screenshots of the maintenance phase the database for the
source image is used.
The screenshot shows the maintenance window after locking the database
for write access. Only red highlighted items are editable. The icons are
exchanged by patterns for a better overview, however patterns cannot be
changed by XPLAB.
Example for an editing maintenance dialog. After locking the database
for write accesses, the user edits an item directly in the maintenance
window. In the edited row a text entry is displayed and a drop-down
list is provided. Not all items can be defined in the training phase
but in the maintenance phase.
Example for visualization and tracing of trained patterns. The big
screenshot shows the TPS image (reduced in size) which contains all
patterns of the test pattern set. The small screenshot shows the class
image, which contains all its patterns. Only printable patterns are
visualized. The trace feature highlights selected patterns.
