Height-width estimation model for a text block

摘要

In a method for establishing a height-width estimation model for a text block, a discrete form of a relationship between the height and the width of the text block is calculated. In addition, at least one coefficient in a polynomial function depicting the relationship between the height and the width is calculated based upon the calculated discrete form and the model is established based upon the calculated at least one coefficient. The model provides a closed form function for estimation of the text block heights associated with one or more widths.
