Abstract :

Arc-form-text is an artistic-text which is quite common in documents such as certificates, advertisements and history documents. Optical character readers (OCRs) fail to read such arc-form-text and it is quite necessary to transform the same to linear-form-text. In this paper, we present an enhancement made to an existing transformation model to overcome the limitations of staircase effect for better readability by OCRs. The method takes the segmented arc-form-text as input. Initially two concentric ellipses are approximated to enclose the arc-form-text and later the enhanced transformation model transforms the characters in the arc-form to linear-form without variations in character size. The proposed method restructures the transformed text to uniform size and is implemented on several upper semi-circular arc-form-text inputs and the readability of the transformed text is analyzed with an OCR.
