Advanced tab
Use this tab to configure image recognition settings.
Page analysis
This group allows you to set the parameters for page layout analysis.
| Option | Description |
|---|---|
| Detect barcodes |
If this check box is selected, barcodes are detected and recognized during the page layout analysis. |
| One Table entire page |
Select this option to create one table per page when outputting to an Excel worksheet. |
Image pre-processing
This group allows you to improve the quality of the image from an OCR point of view, which has impact on the overall page recognition accuracy.
| Option | Description |
|---|---|
| Despeckle |
Select this check box to remove small noise from the image before recognition. |
| Remove texture |
Select this check box to remove noise from halftone images. Scanners often have the possibility of specifying the type of the document as "text", "photo" or "text/photo" (mixed). When "text/photo" or "photo" is selected and "black-and-white" scanning is chosen, the scanners apply a halftone or dithering algorithm to simulate gray levels. In this case, the scanned image contains a lot of noise and a special despeckle algorithm is required to preprocess it before OCR. |
| Deskew |
Select this check box to rotate an image to compensate for skewing for better and faster recognition. |
| Detect orientation |
If this option is checked on, the page orientation is detected during layout analysis, and if it differs from normal, the image will be rotated automatically. |
| Rotate by |
If this option is checked on, the image will be rotated. The option is disabled if the Detect orientation option is switched on. Specify one of the following option for angle of rotations:
