ImageBinarizeMethod

The method to use to binarize color images and video frames. The image binarization process converts a full color or greyscale image to black and white. You can use the following values:

The Global option applies a single threshold to the entire image, and is better for images with a more uniform appearance.

The Local and Enhanced options apply different binarization thresholds to different parts of the image. This produces better results for images with different backgrounds or color schemes in different parts of the image, including black and white images with shaded gray regions.

The Enhanced option performs additional processing to increase the contrast between potential text and background. This can improve accuracy but sometimes increases noise. HPE recommends using this option to process scanned images of historical documents.
