DEFINITION

Classification: 382/289

Determining amount an image is rotated or skewed:

(under subclass 286) Subject matter wherein the properties extracted from an image relate to its inclination or skew angle measured with respect to a reference which may be, for example, a scanning direction or the physical orientation of a sensor array.

(1) Note. This subclass does not include the measurement of image orientation based on alignment marks or fiducials.
