Abstract
A method and apparatus for determining orientation and dot pitch of characters in an image. A statistical neighborhood of a set of dots of an image is determined. The statistical neighborhood includes a set of points and each point is associated with a position and a statistical measure indicative of a likelihood that one or more dots that satisfy a shape and a size criteria are located at that position. A Fast Fourier Transform (FFT) is computed across the set of points of the statistical neighborhood; and based on the FFT of the set of points, a first orientation and a first distance between adjacent dots of characters along the first orientation, and a second orientation and a second distance between adjacent dots of the characters along the second orientation are determined.
