Minimum number of non-ambiguous characters necessary in an image for Auto Rotate to detect the correct orientation

Issue

What is the minimum number of non-ambiguous characters necessary in an image for Kofax VRS Auto Rotate to successfully detect the orientation of the image?

Solution

For Kofax VRS Auto Rotate to successfully detect the orientation of the image and rotate it accordingly, the image must contain a minimum of 8 unambiguous characters in 8-point font or higher.

Ambiguous characters can be read as valid characters in two or more orientations. Examples of ambiguous characters: H,I,O,N,S,X,Z,0,1,6,8, or 9.

Unambiguous characters can only be read as valid characters in one orientation. Example of unambiguous characters: B,K,Q,R,J,Y,3,4, or 7.

If an image contains text in two or more orientations, the text in which at least 8 unambiguous characters are detected first will determine how the image will be rotated.
