If enabled original pictures will be retained during the export of the recognized text to PowerPoint.
Keep text color
If enabled original colors of text are retained during export of the recognized text to PowerPoint.
Enhance local contrast
If enabled engine will increase the local contrast of the image during the preprocessing of the image. Such option may increase the quality of recognition.
The images for which this preprocessing method is effective include:
- Photos or scans of documents with texture or pictures in the background. With the normal binarization procedure, the characters that coincide with darker areas of background may be lost or recognized unreliably. If you apply this method before recognition, such areas are detected, and contrast is increased, with the result that after binarization the characters stand out more distinctly.
- Photos or scans of documents with highly colorful background or text highlighting.
If enabled engine will reduce the noise of the image. Available working options are:
- White noise: this mode may be useful, for example, for uncompressed images with ISO less then 800, for reduced images.
- Correlated noise: this mode may be useful, for example, for the JPEG photos with high compression settings
