Italic detection and rectification

In this paper, a novel italic detection and rectification method without the prerequisite of character recognition is proposed. The merit of the proposed method is that it can be operated directly on a single character so that more accurate statistical information can be obtained. The rationale of our proposed method is that the difference of certain features derived from italic style characters after shear transformation will be canceled, whereas the difference will be more obvious for non-italic style (normal style) characters.
