Abstract
This invention specifically covers one of the many image quality (IQ) metrics that can be part of an overall image quality (IQ) analysis engine. The specific problem with image quality addressed with this metric is that of printed text. Analytical outline font characters are used to represent certain traits of existing text characters, allowing proper image quality analysis while simplifying image processing. Preferably, a set of analytical outline font characters are used, with each representing a different trait.
