6.10.2   Steps for Working With the OCR Training File Browser

This section quickly guides you through a possible application workflow with the OCR Training File Browser. More detailed information on the functionality of the OCR Training File Browser can be read in the sections corresponding to each of the windows within the OCR Training File Browser.

1. Open the Training File Browser either via the corresponding toolbar button or from the OCR Classifier tab within the OCR 助手.

2. Load an existing training file or create a new training file via the corresponding toolbar buttons or the corresponding entries in the drop-down menu File. If several training files should be used or inspected, all of them can be loaded into the OCR Training File Browser.

3. If required, it is possible to add samples to the training file with the training file functionality of the OCR 助手 if required.

4. Choose a classifier via the drop-down menu Classifier ▹ Load Classifier to classify your samples. If you have an own or previously trained classifier, you can load it. Otherwise one of the trained OCR classifiers provided by HALCON can be selected.

5. Inspect and/or edit the contents of training files. This can include adding new samples, deleting samples, combining existing samples for a new training file or adding sample variations as well as checking for classification problems. Use the Training File Window to edit the training file and the Sample Inspection Window to inspect and edit samples.

6. Save changes, for example, via File ▹ Save Training File.

7. Use the training file within an OCR application or continue to prepare an application with the OCR 助手.

Note that all actions can be undone or redone by selecting Undo or Redo in the menu Edit to reverse or repeat changes, respectively.
