The Inspection section helps you to find a solution to a segmentation problem. Therefore, the embedded window shows only the content of the region of interest. By choosing an option from the combo box, intermediate results for different parameters as well as filtered images or symbol candidates can be viewed. By adapting parameters on this tab, changes in the segmentation process may be observed within this window which may be more helpful than just viewing the final result in the Graphics Window.
The following table can help you to solve segmentation problems by adapting the correct parameters.
| Intermediate Step | Observation | Possible Solution |
| Orientation Correction | The text appears rotated. | Adapt the minimum and maximum angle for Line Orientation in the dialog Text Orientation or clip the ROI. |
| Slant Correction | The text appears slanted, for example, printed in italics. | Adapt the minimum and maximum angle for Symbol Slant in the dialog Text Orientation. |
| Filtered Image | The characters are hard to detect in the filtered image. | There may be not enough contrast to segment the characters. Adapting the Stroke Width may help to solve this problem as well as it influences the filter size. Try to enhance the image quality. |
| Extracted Foreground | Not all characters are detected as foreground. One character is detected as two parts of the foreground. | Adapt the parameters in the dialogs Symbol Size and Symbol Fragmentation until they correspond to the appearance of the characters. Try to enhance the image quality if, for example, the contrast is low. |
| Best Symbol Candidates | No symbol candidates or not all symbol candidates are found. | Note, that it is not necessary that all symbol candidates are found here as only the best candidates are displayed. Check if the parameters in the dialogs Symbol Appearance, Size and Shape correspond to the appearance of the characters. That is if the characters appear white on black background, the corresponding parameter has to be set. |
| Line Geometry | The extracted line does not match the text orientation. | Adapt the Baseline Tolerance in the dialog text layout and check if candidates are displayed. |
| Symbol Results | No results or incorrect results are found. | Check if the parameters in the dialogs Symbol Appearance, Size and Shape correspond to the appearance of the characters, that is, if the characters are composed of single dots (dot print), the corresponding parameter has to be set. |
Please note that if there are problems with the OCR, first of all the image quality should be checked. Only if there is nothing to enhance about the quality and therefore the training images are representative for the images in the application, parameters should be changed.
