Partition
This is a function to divide adjacent characters by specifying a
character width when those characters are too close to be cut out one
by one.
Using "Segment pre-process filter" in the image filters enables to set
the erosion filter to divide the closely-attached characters. It is helpful
to cut out the characters such as thin characters and dotted
characters when the erosion filter cannot be used.
As this process is performed based on the fixed character width
specified, the function cannot be used when the character widths vary
according to each character.
1.
Select "Yes" in "Partition".
Although it has been set to "Yes", the partition cannot be executed if the width of the segmented character
is not more than 1.5 times of the specified value in the next "Character Width". When there is no characters
with a size more than 1.5 times of character width, this process cannot be executed.
2.
Set the width of the target characters in "Character Width".
Characters are divided at optimum positions to be found around the specified character width.
Segmented Character Size
Set limits on the size of the characters to be cut out. It is helpful in eliminating foreign objects or cutting out only
the characters with sizes in a certain range.
The list showing the area, width and height of each
character is displayed. Set the maximum and minimum
values according to the list.
Selecting a number in the list displays the character box
of the data in light blue.
1.
Set "Max. Area" and "Min. Area".
The "Area" mentioned here is the number of the green pixels to be displayed on the window when
executing Segment with the F2 key.
2.
Set "Max. Width", "Min. Width", "Max. Height" and "Min. Height".
The "Width" and "Height" mentioned here is the width and height of the red border surrounding each
character to be displayed on the window when executing Segment with the F2 key.
