Which model should I use?
In the Graphical Configuration Page, you can choose different models depending on your needs.
This wiki page tries to help you on which model to select. For more technical/deeper explanations have a look on Neural-Network-Types.
Digit Models
For digits on water meters, gas-meters or power meters you can select between two main types of models.
dig-class11
This model can recognize full digits. All intermediate states shown a "N" for not a number. But in post process it uses older values to fill up the "N" values if possible.
Main features
- well suited for LCD digits
- with the ExtendedResolution option is not supported. (Only in conjunction with ana-class100 / ana-cont)
dig-class100 / dig-cont
These models are used to get a continuous reading with intermediate states. To see what the models are doing, you can go to the Recognition page.
Main features
- suitable for all digit displays.
- Advantage over dig-class11 that results continue to be calculated in the transition between digits.
- With the ExtendedResolution option, higher accuracy is possible by adding another digit.

dig-class100 vs. dig-cont
The difference is in the internal processing. Take the one that gives you the best results.
Analog pointer models
ana-class100 / ana-cont
For pointers on water meters use the analog models. You can only choose between ana-class100 and ana-cont. Both do mainly the same.
Main features
- for all analogue pointers, especially for water meters.
- With the ExtendedResolution option, higher accuracy is possible by adding another digit.

ana-class100 vs. ana-cont
The difference is in the internal processing. Take the one that gives you the best results. Both models learn from the same data.
