7.5.4.1   Select or Save an OCR Classifier

When using a previously trained classifier, you can choose between either

• a Pretrained Classifier from one of the classifiers that are available for HALCON (see Solution Guide I, chapter 'OCR' for a more detailed description of the available pretrained OCR classifiers) or
• a previously trained classifier from file that can be selected via the Browse button next to the combo box for HALCON classifiers.

When deciding which pretrained classifier should be used, it may help to view details of the OCR classifier by clicking the button with the magnifying lens located right of the selection for pretrained classifiers.

If a new classifier should be trained, a Training File has to be used as a basis for training a new classifier. Therefore, select the radio button Training File and continue by loading a training file with the Browse button next to the text field. To start the creation of a new training file, click the button New. After a new training file has been created, samples can be added to the training file and then it has to be saved via the button Save before it can be used for training. To look at a currently or previously created training file and maybe edit it, open the Training File Browser which provides an overview of the content of training files which can easily be modified.
