11.14.3.6. Segmentation
Goal
The characters are separated from each other with the help of segmentation. The module
makes use of various automatic methods. If these automatic methods do not lead to the
desired results, various segmentation settings can be entered manually.
Characteristic
The following settings/results are available:
Min. character
height [px]
The minimum height of the character to be detected is specified.
Max. character
height [px]
The maximum height of the character to be detected is specified.
Min. character
width [px]
The minimum width of the character to be detected is specified.
Max. character
width [px]
The maximum width of the character to be detected is specified.
Min. cluster size
[px]
The minimum number of pixels which must be contained by a seg-
ment in order to be detected as a character
Max. cluster size
[px]
The maximum number of pixels which may be contained by a seg-
ment in order to be detected as a character
Smallest outlier If the requirements concerning height, width and cluster size are fal-
len short of, the detected segment is disregarded.
Largest outlier If the requirements concerning height, width and cluster size are ex-
ceeded, the detected segment is disregarded.
Vertical pixel
pitch [px]
The vertical pixel pitch for fonts which are made up of individual pi-
xels is specified.
Horizontal pixel
pitch [px]
The horizontal pixel pitch for fonts which are made up of individual
pixels is specified.
Distribution The following options are available:
Standard Fixed distribution of the characters is assumed. Cha-
racter spacing and angle do not vary.
Variable Distribution of the characters with regard to spacing,
angle and size may vary.
Dynamic Distribution of the characters with regard to spacing,
angle and size may vary greatly.
