10. Appendix D: Checking Recognition
Quality
The executable file can be run in standalone mode. In this mode video is taken fron video
wagon.exe
archive. For train segmentation one can use either video or file with information of each carriage
passing.
To check the quality of recognition:
1. Launch
wagon.exe
2. Choose file open configuration from XML file item from the menu.
3. Choose XML file of recognizer settings.
4. If it is necessary edit this configuration file by editing the follow fields:
Configuration/video source/iplus archive/folder — video archive folder
Configuration/ocr data/ocr data item/path — ordering information folder (creating on
Module installation)
Configuration/segmenter/type — data type. This data is used for train segmentation.
Possible values:
–
ray emulation
tion/segmenter/ray emulation group defines an algorithm parameters. Edit TopLine
and BottomLine fields only as they define top and bottom lines for train partition
–
ray from timing file
tion/segmenter/ray from timing file group defines an algorithm parameters. There
is a path to the information file in FileName field.
Configuration/segmenter/MinTimeBetweenTrains — minimal timeout of trains passing
(in seconds)
Configuration/Localizator — fields that are used for number localization algorithm con-
figuration:
– TopLine / BottomLine — top and bottom number localizer lines (%)
– NumberWidth / NumberHeight — approximate carriage numder width/height (%)
Note: It is recommended to configure right train partition first and then set localizator lines parameters.
