### Image Binarization

Image binarization, available in IntelliText OCR only, converts grayscale images to black and white (binary) to optimize the readability of poorly segmented characters.

The Auto setting is satisfactory for most applications. However, Fixed Template allows nuanced control of binarization parameters.

In the example below, multiple characters are not detected due to segmentation problems when Image Binarization is set to Auto. When Image Binarization is set to Fixed Template, the cause of the segmentation problem is revealed to be poor binarization in the original grayscale image.
