The Image Clean-up Options dialog box allows an image to be temporarily enhanced prior to OCR processing. Temporary image enhancements allow the optimization of OCR results.
- Deskew image: Straighten crooked images.
- Despeckle image: Remove undesired noise from an image.
- Specify the maximum size of noise to be removed(in pixels): The maximum size of the noise to be removed. Size is specified as both width and height. For example, setting this option to 2 will remove all noise that is equal to or smaller than a 2 pixel x 2 pixel square.
- Rotate image: Automatically or manually rotate an image.
- Automatically: The direction in which text flows on the page will be detected. The image will be rotated so the text flows horizontally (left to right).
- By this amount: The amount by which the image will be rotated. An image can be rotated by 90, 180, or 270 degrees.
- Line removal: Removal of lines from an image.
- Horizontal: Removes horizontal lines from the image. Characters that are damaged due to the line removal will be repaired.
- Vertical: Removes vertical lines from the image. Characters that are damaged due to the line removal will be repaired.
